What does the 'lambda ' warning light on the dashboard mean?

The exhaust gas oxygen sensor (EGO or O2), or lambda sensor, is the key sensor in the engine fuel control feedback loop. The computer uses the O2 sensor's input to balance the fuel mixture, leaning the mixture when the sensor reads rich and richening the mixture when the sensor reads lean. Lambda sensors produces a voltage signal that recognises the amount of unburned oxygen in the exhaust. An oxygen sensor is essentially a battery that generates its own voltage. When hot (at least 250 degrees c.), the zirconium dioxide element in the sensor's tip produces a voltage that varies according to the amount of oxygen in the exhaust compared to the ambient oxygen level in the outside air. The greater the difference, the higher the sensor's output voltage. Sensor output ranges from 0.2 Volts (lean) to 0.8 Volts (rich). A perfectly balanced or "stoichiometric" fuel mixture of 14.7 parts of air to 1 part of fuel gives an average reading of around 0.45 Volts. The lambda sensor's output voltage doesn't remain constant, however. It flip-flops back and forth from rich to lean. Every time the voltage reverses itself and goes from high to low or vice versa, it's called a "cross count." A good O2 sensor on a injection system should fluctuate from rich to lean about 1 per second. If the number of cross counts is lower than this, it tells you the O2 sensor is getting sluggish and needs to be replaced. Most lambda sensors will cycle from rich to lean in about 50 to 100 milliseconds, and from lean to rich in 75 to 150 milliseconds. This is referred to as the "transition" time. If the O2 sensor is taking significantly longer to reverse readings, this too is an indication that it is getting sluggish and may need to be replaced. Observing the sensor's waveform on a scope is a good way to see whether or not it is slowing down with age. If the sensor becomes sluggish, it can create hesitation problems during sudden acceleration. Heated Oxygen Sensors To reduce the warm-up time of the Lambda sensor, an internal heating element may be used. Heated O2 sensors can reach an operating temperature of as high as 500 degrees C in as little as eight seconds! Shorter warm-up time means the system can go into closed loop fuel control sooner, which reduces emissions and improves fuel economy. Heating the sensor also means it can be located further downstream from the exhaust manifold. A lambda sensor's normal life span is 30,000 to 50,000 miles. But the sensor may fail prematurely if it becomes clogged with carbon, or is contaminated by lead from leaded petrol or silicone from an antifreeze leak or from silicone sealer. As the sensor ages, it becomes sluggish. Eventually it produces an unchanging signal or no signal at all. When this happens, the Check Engine Light may come on, and the engine may experience drivability problems caused by an overly rich fuel condition. Poor fuel economy, elevated CO and HC emissions, poor idle, and/or hesitation during acceleration are typical complaints. If the average voltage from the lambda sensor is running high (more than 0.50V), it indicates a rich condition, possibly due to a bad MAP, MAF or Air Flow sensor or leaky injector. If the average voltage reading is running low (less than 0.45V), the mixture is running lean possibly due to a vacuum leak or because the sensor itself is bad. If the lambda sensor continually reads high (rich), it will cause the engine computer to lean out the fuel mixture in an attempt to compensate for the rich reading. This can cause lean misfire, hesitation, stumbling, poor idle and high hydrocarbon emissions (from misfiring). If the lambda sensor continually reads low (lean), it will cause the engine computer to richen the fuel mixture. Injector pulse width will increase causing fuel consumption and carbon monoxide emissions to go up. Constant rich fuel mixture can also cause the catalytic converter to overheat and it may be damaged. If the lambda sensor's output is sluggish and does not change (low cross counts & long transition times), the engine computer will not be able to maintain a properly balanced fuel mixture. The engine may run too rich or too lean, depending on the operating conditions. This, in turn, may cause drivability problems such as misfiring, surging, poor idle, and high emissions. If a heated sensor has a faulty heating circuit or element, the sensor can cool off at idle causing the system to go into open loop. This usually results in a fixed, rich fuel mixture that will increase emissions. Sometimes an apparent lambda sensor problem is not really a faulty sensor. An air leak in the intake or exhaust manifold or even a fouled spark plug, for example, will cause the lambda sensor to give a false lean indication. The sensor reacts only to the presence or absence of oxygen in the exhaust. It has no way of knowing where the extra oxygen came from. So keep that in mind when diagnosing oxygen sensor problems. The lambda sensor is also grounded through the exhaust manifold. If rust and corrosion of the manifold gaskets and bolts is creating resistance, it may affect the sensor's output. To rule out a bad ground, use a digital volt meter to check for a voltage drop between the sensor shell and the engine block. More than 0.1v can cause a problem. Lambda Sensor Checks A good lambda sensor should produce a fluctuating signal that changes quickly in response to changes in the oxygen level in the exhaust. The best way to check the sensor is to observe the sensor's output on a waveform scope or oscilloscope. A scope will display not only the sensor's minimum and maximum voltage readings, and average voltage reading, but also its back and forth voltage oscillations from rich to lean. Sensor output can also be read directly with a 10K ohm impedance digital voltmeter, or some code readers. CAUTION! Never use an ohmmeter on a zirconium O2 sensor in an attempt to check the sensor because doing so can damage it. And never jump or ground the sensor's leads. The lambda sensor's voltage reading should have a minimum reading of 200 millivolts (0.20 V) and a maximum reading of 800 millivolts (0.80 V). If the sensor reading is averaging low (under 400 millivolts) or high (over 500 millivolts), the engine may be running rich or lean because of some other problem. If the sensor's output voltage never gets higher than .60v and never drops to less than 0.30 V, it needs to be replaced. The same is true if the sensor's output is sluggish or doesn't change. To check the sensor's response to changing oxygen levels in the exhaust, first create an artificially lean condition by pulling a large vacuum line. When extra air is introduced into the engine, the sensor's voltage output should drop to 0.2 V. To check the sensor's rich response artificially richen the mixture by, if possible, clamping the return fuel line momentarily. This will force more fuel through the injectors and should cause the O2 sensor's voltage to increase to 0.8 V. If the sensor's output fails to respond to the changes you've created in the oxygen level in the exhaust, it's time for a new sensor. Zirconium sensors can also be bench tested by heating the tip with a propane torch while monitoring the sensor's voltage output with a digital voltmeter. Connect the positive voltmeter lead to the signal wire (normally black) coming out of the O2 sensor and the negative voltmeter lead to the sensor's outer shell. Then heat the tip of the sensor with the propane torch. The tip should be hot enough to turn cherry red, and the flame must enter the opening into the sensor tip. If you get a voltmeter reading above 600 millivolts (0.6 Volts), and the reading quickly changes as you move the flame back and forth over the tip, the sensor is okay. A low reading or one that is slow to change means the sensor needs to be replaced. Removing Lambda Sensors Removing the sensor when the engine is cold will lessen the odds of stripping the threads in the exhaust manifold. Penetrating oil may be needed to loosen rusted threads. Once the sensor has been removed, the threads in the manifold should be cleaned before the new sensor is installed. Apply graphite grease to the sensor threads unless the threads are precoated. Replacing Lambda Sensors Everybody knows that spark plugs have to be replaced periodically to maintain peak engine performance, but many people don't realise the same goes for oxygen sensors. As long the lambda sensor is working properly, there's no reason to replace it. But after 30,000 to 50,000 miles of being constantly bathed in hot exhaust gas, a build up of deposits on the sensor tip can make it sluggish. If there's enough clinker on the sensor tip, the sensor may produce little or no voltage at all. This produces a false "lean" signal that makes the computer think the engine needs more fuel, which it doesn't but gets anyway. This creates a rich fuel condition that kills fuel economy and sends carbon monoxide and hydrocarbon emissions soaring. The engine may also experience additional drivability problems such as surging or hesitation. The same kind of thing can happen if the lambda sensor is contaminated by deposits from sources other than normal combustion. It only takes a couple of tankfull's of leaded petrol to ruin an lambda sensor (and catalytic converter). A lead contaminated oxygen sensor will typically have light rust coloured deposits on the tip. Another source of sensor contamination can come from silicone poisoning. If somebody used the wrong kind of silicon sealer to seal up a leaky rocker box cover or manifold gasket, silicone can find its way into the engine and foul the sensor. Silicates, which are used as corrosion inhibitors in antifreeze, can also cause the same kind of poisoning. Sources here might include a leaky head gasket or racks in the combustion chamber. Silicone deposits on the sensor tip will have a shiny white to grainy light gray appearance. If the engine has an oil consumption problem due to worn valve stem seals, piston rings and/or cylinders, a build up of heavy black to dark brown oily deposits on the sensor tip can make it sluggish. If the deposits have a black powdery consistency, the fuel mixture is running rich. This may be due to the sensor already having failed, or it might be due to something else such as a leaky injector or a computer problem, or constant short journeys where the cold start system doesn't have time to come off (open loop) known as housewives car. When ever you suspect a lambda sensor problem, the first thing you should do is scan for any codes that would implicate the sensor circuit. A code by itself doesn't necessarily mean the sensor is bad, however. It might be a wiring problem or something else. So always follow through with the diagnostic check to diagnose what's wrong before you replace anything. If you don't find any codes, that doesn't necessarily mean the lambda sensor is okay. In many instances, a sluggish sensor may not be bad enough to record a fault code but will still be causing an emissions or drivability problem.

What is wrong if the sunroof on your Volvo 960 is not leaking out of the drains but from the inside track?

Hi I just got my 97 960 , sun roof loked at it was leaking on both sides. I watched a guy do it that had years of experience. He is not always sure of were the water gets in . Seems like a lot of trial and error.

He cleaned off the seal around the glass with paper towel (the seal that looking from the top goes over the glass by a 1/2 " } . He had a piece of plastic {like a knife} and got it under the seal and blew any dirt out with compressed air.Then he used a caulking gun with a urathane cartridge in it {buy at the auto store for puting in windshields} and got the urathane under the seal all the way around. For any cleanup he squirted the excess urathane with a soppy water and ran a flat razor blade around the glass .Wipe off excess on per towel as you go. Also to check your drains there is a hole in each corner of the sun roof ,. Blow each hole with compressed air . At the front you should hear air at the bottom corner of each side of the wind shield. I didn't think it would work but it has rained yesterday and no leak !

Secondly when i shut the power sun roof , sometimes you can still hear the air sound so I have to bump the roof toggle switch to get a tight shut off. A Volvo mechanic showed me how to adjust it. There is an adjustment on each side of the sun roof .You can see it from insde the car on the sun roof linkage toward the back. Loosen off the small bolts on each side and push up on the glass.Tighten bolts back up.

Answersun roof has a tube at back of track which allow water to run off . this track if clogged will cause water to back up and run over side of track into car. better to put a vaccum tube on it than to blow thru which may clog it worse. J.R. good luck

How many gears does your 1982 Suzuki TS 125 ER have?

My TS 100 had 5, but my TS 250 had 6. I would imagine yours has 5. The TS125 has a weak gearbox and often the 2º axle bearings break, the simphtoms start by a noisy 4º and 6º,later on you lose the 6º , and you discover you have a new dead point or neutral afther or up 5º, that´s probably you´re asking for.

How do you get the check engine light codes on a Volvo 940?

1. Purchase an OBD II code reader machine from an auto parts store.

2. Or the easier, cheaper way: take your vehicle to Aamco Transmissions or Midas shop and they will check it for free!

If the Volvo is 1995 or newer, they can pull the codes very easily.

If it's 1994 or older, they can pull the codes but it takes more labor.

Whichever shop you go to may charge you if your Volvo is 1994 or older. But you can always try to negotiate the price down and see if they'll go for it.

The Aamco I took my '94 to wanted $98. I said forget it, but since they took so long with my car they through in the test free.

What is an amplifier?

A device used to make an instrament louder, usually an electric guitar. Sound signals have a certain amplitude behind them (power). If the signal is week, it is difficult to hear and transmit. Therefore, you need an amplifier to add power to a signal in order for it to be heard and transmitted.

Where are the timing marks 1996 Volvo 2.9 960 engine?

There are six timing marks on the 960 engine that you need to line up to get timing right. There are two arrows etched into the metal on the camshaft gears where the belt goes on. Next those arrows line up with the cut outs in the plastic of the timing cover. Basically the timing belt cover, covers the two camshafts but also SHOWS where the arrows need to line in between the two camshafts. The two arrows on the camshaft gears need to point to the cutouts on the plastic. Its more difficult to explain than it really is to do. Lastly there is a degree marking on the crankshaft when looking down at it from top. Also a faint marking on the block near the crankshaft as well. If you don't have any marking down by the crankshaft you will need to buy a tool that stops the crankshaft from rotating. This tool fits into a plug near the starter and correctly positions the crankshaft where it needs to be for correct timing.

Transmission Fluid

How do you fill the transmission on your 1996 Volvo 960 There is no dipstick?

There is a transmission dipstick on the Volvo 960 (in the UK the 960 has a 3 litre engine - though I believe that in the States the car is known as the 940).

Open the bonnet (hood) and stand at the front. Locate the OIL dipstick on the right as you look at the engine. Draw an imaginary line from you to the OIL dipstick -then to the bulkhead. The transmission dipstick is located an arms-length down from where the imaginary line hits the bulkhead. It's awkward to find and not easy to access.

The transmission oil dipstick has a yellow top (you will probably need a flashlight to peer down and see it) with a square recess. The square recess is designed to take a 3/8 LONG extension bar to pull it out. The dipstick is actually held in place by a spring-clip.

Alternatively, you can crawl underneath the car from the left hand side - driver side in the States, Passenger side in the UK...) and remove the dipstick by reaching up. This is probably the easiest option.

There's a couple of photos of the transmission dipstick location on my website www.glennsmart.btinternet.co.uk Click on 'Volvo 960' from the drop down menu.

On 1995 and later US market 960s, there is no transmission dipstick. "Logic" at the time was that you NEVER had to change the transmission fluid. We now know this to be faulty "logic". Fluid must be filled from a fitting on the upper side of the transmission.

What is the definition of amplifier?

If you are speaking of the radio amplifier, it takes the low powered signals from the radio and increases them for output to the speakers. Amplifiers usually have some provision or internal programming for splitting the signal so lower frequencies go to subwoofer and midbass speakers while higher frequencies go to tweeters.

Why does your 1996 Volvo sound like driving on a washboard when you brake at fory miles per hour?

I have had that symptom several times. It appears to be associated with wear of the rotor, which seems to happen "normally". If you feel the rotor, there is a rough edge around the edge, and I figure the side of the brake pad rubs that ridge and gives you that effect.

In any case, replacing the rotor does the trick. One shop told me that they replace the rotor whenever the pads are replaced.

A friend reports that the same symptom in his BMW 3 series was cured by lubing the pins on which the pad moves in and out on, I con't confirm that.

How to open a Volvo door that will not open?

If the door won't open from the outside when you press the handle, you need to take apart the interior part of the door and the mechanism. There is a barrel that slides in a groove that has jumped out causing the door to not open from the outside. If you have auto locks they will not work either. Only opening the door from the inside will work since that pushed the lock from another position. Hope that helps.
