Check Engine Light

"Ruddy light" typically refers to a warm, reddish glow often associated with sunsets or sunrises. It can evoke feelings of warmth and calmness, creating a picturesque atmosphere. The term "ruddy" itself describes a reddish or rosy hue, suggesting a vibrant and lively quality to the light.

You may have to repeat this several times until you accomplish the task. Select the odometer total miles with the trip reset switch. Turn off ignition and then turn on again depressing the reset switch and holding it until the maint light begins blinking. Continue pressing on the switch until the maint light goes out.

Have vehicle scanned to determine the problem

That depends on the year make and model. Some codes require a self test to pass three times in a row, which can take weeks depending on driving habits.

knock sensor is going bad or is bad

The check engine light means there is a problem with the emission systems on the vehicle. The service engine light means that a regular schedule service is needed. Most of the time this means you need an oil/filter change.

you can either purchase a computer programmer ($200-$350+) that will allow you to check and clear codes as well as adjust computer settings for maximum performance or take the vehicle to most auto parts stores that can check the codes for free.

p0105 MAF sensor circuit

p0130 02 Circuit malfunction bank 1 Sensor 1

p0150 02 Circuit malfunction bank 2 sensor 1

p1445 not a generic code need vehicle info to gues

All these codes are faulty Circuit codes. So more likly a bad wire, fuse or computer than all the sensors.

Looking at the list I am going to make a guesses starting from most to least likely:

1stThere is a problem with a damaged or broken wiring harnes at the computer. Get a wiring diagram and prove the wiring is good on all the wires to all the sensors on the list

The ECM that runs all this stuff is bad.. Prove the sensors are not bad before replacing an expensive computer.

Next: All these sensors are faulty, crash or used parts or vandalized?

Try disconnecting the negative battery cable for 5 minutes. If that does not work you will need to use an OBD2 scan tool to reset it.

Could be anything but Check the oil dip stick. If that's ok drive to a VW garage and their sofware will give more details.

If a coil (in a coil-pack arrangement) is bad then the engine is probably misfiring on two cylinders.

You can purchase plastic pliers that are designed specifically for pulling sparkplug wires while the engine is running.

Start the engine, pull one plug wire from the coil pack using the plastic pliers. (don't use metal, you'll get a shock that will change your attitude) Go through the plug wires until you find one that DOESN'T make the engine run worse when you pull the wire. To verify that THAT is the bad coil, pull the OTHER wire and see if it doesn't affect the way the engine is running.

The light is on, because the is a problem with the SRS. Working on the air bag system can be dangerous. For this reason, I recommend you seek professional help.

Remove the battery ground cable for about 5 mins. then put it back on.

Now there is a reason it came on in the first place, If you don't repair the problem it will just come back on again. You need to have the engine scaned with an engine scanner to see what the problem is.

Trouble code P0783 means: A/T 3-4 Shift Solenoid - No RPM Drop At Lockup

The service engine soon light on a 2002 Altima 3.5SE means you need to have some sensors replaced. Depending on when your car was built, it may have 2 or 3 recalls. The major recalls are for a crank shaft sensor and two cam shaft sensors. You wouldn't expect a 'service engine light' to trip on a 2002 model, but this is common to new model year vehicles. The light on my '02 Altima 3.5SE went on last week with only 28k miles. The dealer replaced the sensors and found the light was tripped more than likely from the cam shaft sensors, since a problem with the crank shaft sensor should normally prevent your engine form starting. Get this recall/warranty service done soon. I noticed poor gas mileage and slower acceleration. Cam sensor could cause slight misfires which could bring up your fuel consuption. Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist.

Cylinder #2 Misfire

This can be any number of things from bad spark plugs to catalytic converter, crank or cam sensors to map sensor. Have it scanned, find out what code is stored and that will tell you the problem.

P1280 Injection Control Pressure Out Of Range

The P0443 code translates to: "Evaporative Emission Control System Purge Control Valve Circuit". To find more information on this code, go here: http://www.obd-codes.com/p0443 For a complete list of codes, go here: http://www.obd-codes.com/trouble_codes/

reset the ecu and it will start do this by disconnecting the battery and unplug the ecu and wait an half hour so the ecu can discharge then reconnect and it should start what you may find the the car has a service limit ie so many miles before service after that it goes in to limp mode and then all stop. its an old trick but it does work.

If it flasehes when you turn the ignition on, and continues to flash, then i know on my astra, this is the immobilizer kicking in. Try a different key. if not, see your local garage

if the light is flashing then the system is not finding the "chip" in the key, has the key been dropped and broken recently, is it a new key? if it has broken recently then look for what looks like a chip of dark coloured stone and refit into key if you cannot find this then a main dealer should keep them on the shelf, but you will need the vehicle security number.

As said above, a flashing "engine management light" during cranking means the immobilizer system in the car does not recognise the immobilizer chip in the key, or does not detect a chip at all. The chip is about 5mm long, 3 wide, and 2 deep. In other words "Freaking Tiny". It's very common for them to fall out of the key if dropped, or when the key is opened to change the bulb/battery in the "torch".

It's also possible that there has been a failure in either the Fuel injection system, or in the Immobiliser system, but it's more common for the chips to fall out of the keys, as the chips are so small, most people don't notice them on the ground when they drop the keys.

Depends on the problem, it could mean anything from a new spark plug to needing a new cylinder head and anything inbetween.

I have heard a few different things mentioned. Check on lexusownersclub and post it in the LS400/430 catagory. A very good specialty site. vbd

If your check engine light is blinking that means a cylinder misfire has been detected

Drive in a moderate fashion ( no fast acceleration / decelleration ) and have the

vehicle scanned for any trouble code(s) to diagnose and repair the problem

"EVAP emission system - very small leak

Probable cause

1. Faulty fuel cap

2. Leakage in emission system

3. Faulty vent solenoid
