\n. \n Answer \n. \n. \nI assume you wish to reset your ECU (computer). It really depends on the year. On my 97 626: Remove negative battery cable, depress brakes for 10-15 seconds(to ensure power is completely depleted). Reconnect Battery. This will reset your computer. you may need to put a… code into a factory installed radio (to make the radio work again).\n. \nPlease note: Your ECU needs to "re-learn" how to run your engine, your car may run rough for awhile as the ECU "learns" how to operate your engine. It may take 40 miles or so, its a good idea to do both city and highway driving to make sure the ECU sets itself properly. (MORE)
It is a small square box near the beginning of your air intake. It has two Phillips screws in it and wires coming out of it
The mass air flow sensor is located just after the air cleaner,before the rubber hose that goes to the intake.A little black box attached to an aluminum ,with a 3 wire connecter.
Answer . \nOn a 1998 it is about 3/4 of the way down the drivers side of the motor (4 cyl.) Middle of the block.
Look along the air intake passage front to throtle body; I'm sure it's there somewhere. Many parts houses on the Internet have component locators, try NAPA or Autozone, Shucks....many local libraries have on line resources for auto repair. You might find a component locator there as well. Go buy a H…aynes Auto Repair manual for your car. (MORE)
Its in the air Filter box of your car. Stop using K&N The MAF sensor monitors the air flow into the engine and sends that info to the ECM.
Answer . If you follow the exhaust tubing that leads from the engine. It is located after the exhaust manifold and after the next pipe is bolted together. Sowhere in this area you will find one. It might have just one or it will have one coming off each exhaust header side. It just depends on the …model year. Some models have one after the catalytic convertor also. Again this depends on the year. The O2 sensor will be screwed into the exhaust tubing and will have an electrical connection connected to it. If you are replacing this then spray penetrating oil on it first and let it set awhile then undo the connector and uncrew it from the pipe. Hope this helps. (MORE)
unplug it, if there is no change in how the engine runs it may be bad. the only for sure way is to test it on a sensor tester. There are some MIL codes that will lead to a faulty MAF p0102 maf signal low input p0103 MAF signal high p1100 maf circuit output low during self test p1101 maf se…nsor circuit output low during self test A few that arent so obvious Lean or rich codes fuel trim codes serious lack of power when accelerating lousy gas mileage rough idle or stalling Look for vacuum leaks between the maf and throttle body and dirt or fuzz on the two wires on the sensor itself, these two items are the easiest to cure. Clean the sensor with electrical contact cleaner or maf sensor cleaner, but dont touch the fragile wires, they break easily. (MORE)
The MAF is under the hood (!) - facing the car from the front bumper, it'll be on the right hand side, just to the left of the AIR FILTER box. There is a hose that comes off the airf filter box that runs to the intake manifold. The MAF is inline, and it can be identified by the sensor wire that atta…ches to the firewall side of the hose..

its located under the glove box on the passengers side you need to pop open that panel to get to it
Answer . The 2001 Sienna MAF is on top of the Air filter box on the driver side of the engine. It is mounted with two screws and has an electrical harness attached to it. It could be replaced in less than 5 minutes using only a screw driver.
Ford Engines: . You MAFS (Mass Air Folw Sensor) depending on if you car is a z-tec or duratec would be right in front of you if you open the hood (assuming it's a duratec). It is connected to you MAF tube. If you follow your intake it's the tube right before it coonects to your plastic intake manif…old. On the MAF tube is a little plug that is your sensor. (MORE)
Depending on the vehicle it is generally located in the snorkel between the air filter box and the throttle body.
Yes you can by using Mass Air Flow Sensor Cleaner by CRC. Kragen Auto Parts sells it. This is what the Mass Air Flow Sensor Cleaner by CRC looks like (http://www.autobarn.net/maairflsecl1.html) you can order it online too. After you clean the mass air flow sensor make sure to reset the check eng…ine light. You can reset your check engine by going to Auto Zone or Kragen Auto Parts and ask to borrow the code reader* (it's free all you need is your ID and credit card) to check out the code reader. (MORE)
There are four O2 sensors on that vehicle assuming you have a 4.3L engine. The 2.2L engine I believe has three. They are accessible underneath the vehicle and are threaded into the exhaust system. One is located on each end of the cat converter and the other ones are directly behind each bank of cyl…inders on the exhaust pipe. Each has a four wire harness attached that can be unplugged.. I can't tell you where it is SPECIFICALLY on your vehicle, but all Oxygen sensors are on the exhaust, and most are as close to the heads as possible, usually just after the exhaust manifold, screwed into the headpipe.

it on the hose between the air filter and the engine on top of the hose , a square 1 by 1 plastic piece.
The MAP Sensor on the GMC Sonoma is located in the enginecompartment just to the left of the alternator. The MAP Sensor isusually colored silver or shows a gold tint.
The mass air flow sensor should be in the air intake tube attached to the air filter. Unclip the electrical harness and unscrew the Phillips screws holding it in.
The mass air flow (MAF) sensor measures the mass of the air entering the engine. Because air mass varies with air temperature (cold air is denser than warm air), measuring air mass provides the PCM with a very acurate way of determining the correct amount of fuel to obtain the ideal fuel/air mixture…. - Haynes Repair Manual #36071 (MORE)
directly on the intake tube its right in front of you with a clip on it and two torx head screws holding it on.
The 2003 GMC ambient air temperature sensor is located on thebottom of the drivers side mirror. If you look up at the bottom ofthe mirror you will see the sensor.
Follow the rubber hose that goes to the intake manifold at the throttle body, it is the square part that bolts together to it you will see some wires there.
It senses the amount of air being drawn into the engine and communicates with the computer to adjust fuel levels accordingly.
The mass airflow sensor, on Most VW Jetta Mark IV, is located on the air line that goes from the air filter to the intake.
i need more info they put several ,, in mine i have whats called a T-5 its a 5 speed manual transmission but i have the 2.8v6 it all depends what kind of 93 sonoma
Post more info it could be so many things , will it even turn over?
It determines the Mass of the Air Flowing into the engine. The engine computer must know how much air is flowing into the engine to determine how much fuel to inject into the cylinders to get the appropriate fuel-air mixture.
Depends on the engine, on the 4.3 TBI its on the passenger side screwed into the head between the first and second plug.
There are several 02 sensors on that vehicle and they are all threaded into the exhaust system at various points.
the mass air flow sensor detects the flowing of mass air into the engine while the mass air flow meter detects the amount of mass air flowing into the ingine.
There are alot of grease fittings on this truck, i dont know all the names for the places, but here goes. 2 Fittings where the steering shaft attaches to the bar that turns the wheels 2 Fittings behind the front wheels 2 Fittings behind rear wheels 4 more fittings under the truck engine …area, but I dont know the areas (MORE)
It is located in line with the air filter just before the big black air intake tube on the right-hand side of the engine. You'll have to remove a few bolts to get to it...
it is attached to the throttle body the left side of it should have i think 3 wires coming out of it
Mass Airflow Sensor Operation The Mass Airflow (MAF) sensor directly measures the mass of air being drawn into the engine. The sensor output is used to calculate injector pulse width. The (MAF) sensor is what is referred to as a "hot-wire sensor". The sensor uses a thin platinum wire filame…nt, wound on a ceramic bobbin and coated with glass, that is heated to 200*C (417*F) above the ambient air temperature and subjected to the intake airflow stream. A "cold-wire" is used inside the (MAF) sensor to determine the ambient air temperature. Battery voltage from the EEC power relay, and a reference signal and a ground signal from the PCM are supplies to the (MAF) sensor. The sensor returns a signal proportionate to the current flow required to keep the "hot-wire" at the required temperature. The increased airflow across the "hot-wire" acts as a cooling fan, lowering the resistance and requiring more current to maintain the temperature of the wire. The increased current is measured by the voltage in the circuit, as current increases, voltage increases. As the airflow increases the signal return voltage of a normally operating (MAF) sensor will increase. Testing 1. Using a multimeter, check for voltage by back probing the (MAF) sensor connector. 2. With the key ON , and the engine OFF , verify that there is at least 10.5 volts between the VPWR and GND terminals of the (MAF) sensor connector. If voltage is not within specification, check power and ground circuits and repair as necessary. 3. With the key ON , and the engine ON , verify that there is at least 4.5 volts between the SIG and GND terminals of the (MAF) sensor connector. If voltage is not within specification, check power and ground circuits and repair as necessary. 4. With the key ON , and the engine ON , check voltage between GND and SIG RTN terminals. Voltage should be approximately 0.34-1.96 volts. If voltage is not within specification, the sensor may be faulty. Removal & Installation ( 4.6L & 5.4L) 1. Disconnect the negative battery cable. 2. Release the air cleaner clamp and separate the air cleaner halves. 3. Remove the grommet from the air cleaner housing and slide the grommet down the hardness. 4. Remove the (MAF) sensor plate and (MAF) sensor from the air cleaner. 5. Detach the (MAF) sensor from the harness. 6. Remove the retaining nuts and remove the (MAF) sensor. 7. Installation is the reverse of removal. (MORE)
Air tube leading away from air filter box. Sometimes attached to the top of the air filter box
Most MAF sensors are located in the air duct between the air filter box and the throttle body. Remove the electrical connector. Then loosen the hose clamps that hold the MAF in place. Swap out the sensor and tighten the clamps.
under the glove box, follow the wires coming through the boot on the firewall. it's mounted vertically under the lower passenger side dash
A 3.1 does not use a mass air flow sensor. It uses a MAP sensor. It is usually mounted on the firewall or the top back side of the engine. It will be about 3 inches long, 1 1/2 wide, black, and on the bottom side of it there will be one vacuum hose and one electrical connection. They are usually bol…ted on with two small screws. (MORE)
i think it is bolted on to the throttle body.it is black with a plug in on it
If the MAF sensor is clearly wrong, then the computer will calculate a substitute value and it will turn on the MIL indicator on the dash. If it is partially wrong, the MIL might not indicate, but performance will suffer. To test it, you will need a scan tool and the proper diagnostic procedures. Se…e the shop manual. Do not just replace the MAF sensor unless you have proved that the computer or the wiring is not at fault, otherwise you might damage the new part. (MORE)

The MAF sensor would be found in the snorkel between the air filter box and the throttle body.
On a 1999 Ford Expedition : The Mass Air Flow Sensor is located INSIDE the round shaped plastic housing , between the engine air filter housing and the engine airintake tube
On a 2002 Ford Explorer : The Mass Air Flow sensor is between the top of the engine airfilter housing and the big engine air intake tube
On a 2002 Ford E-150 : The Mass Air Flow Sensor is INSIDE a round shaped plastic housing located between the engine air filter and the engine air intaketube
In the exhaust pipe in front of the catalytic converter...close to engine in crossover pipe
You can unplug it and your car will be in limp mode, but bypassing is not a good idea. It is the single most important sensor on any car and determines air/fuel ratio.
A mass air flow sensor can be found on vehicles with fuel injectors. There are many step by step videos and written instruction manuals that show how to take off this sensor and clean it with a cleaning product purchased at an automotive store.
First have to be sure it isn't the MAF. Simply cleaning the MAF is not enough sometimes. With the vehicle running, tap on the MAF plug... Any difference? Then with vehicle running, unplug the MAF... Does it run better? If so, MAF is bad. If these check out fine, then it could be a dirty throttle bod…y, dirty air filter etc. (MORE)
