Where is the mass air flow sensor for a lincoln navigator located?


The MAF sensor is mounted to the Cold Air Intake between the front port and the throttle body.

The P0456 is not your cause here. If there are no other codes present other than the P0456, try unplugging the mass air flow sensor and see if the sputtering goes away and if so, replace the mass air flow sensor. You could also have a clogged fuel filter or a bad fuel pump (low pressure)

P0102 - Mass Air Flow Sensor Circuit Malfunction

The mass air flownissan-maxima-maf-sensor.jpg or MAF sensor is placed in the intake air duct between the air filter and the engine intake manifold. The MAF sensor measures the amount of intake air flow. The MAF sensor converts the air flow measurement into a voltage or frequency signal, with the voltage or frequency changing proportionally to the amount of air flow. The air flow sensor signal is monitored by the engine computer (ECM). The engine computer (ECM) uses the mass air flow signal to know the engine load and to calculate the proper amount of fuel injected. If the signal from the mass air flow sensor is out of expected range, the ECM detects a fault and sets the code P0100. For example, the mass air flow sensor signal could be higher than expected when the engine is not running or lower than expected with the engine running. A car with the code P0100 may have some driveability issues, such as stalling, lack of power, surging, hesitation, etc. In some cars, the code P0100 can cause the fail-safe mode where the engine speed would be limited to 2,500 - 3,000 rpm.
If there are other trouble codes present, they might need to be looked at first. Checking the freeze frame may help, as it may contain some important information. The freeze frame is a snapshot of the engine parameters at the moment when the fault was detected. The freeze-frame may show whether the vehicle was running or stopped, whether the air-fuel ratio was lean or rich, was the engine was cold or warmed up at the time of the malfunction. Read more about the freeze frame.


Read more about mass air flow sensor.

What could cause the code P0100:
- faulty or contaminated mass air flow sensor
- open or short in the mass air flow sensor electrical circuit
- open or short in the sensor power or ground circuit

- other electrical problem with the MAF sensor wiring, (corroded wires, bent terminals, bad ground connection, burned fuse, etc.
- vacuum leaks
- restricted air flow at or before the air filter
- wrong air flow sensor installed
- problem with ECM





P0102 - Mass Air Flow Sensor Circuit Low

The mass air flow or MAF sensor measures the amount of air entering the engine. The engine computer (ECM) uses the mass air flow signal to calculate the amount of fuel injected (read more how the MAF sensor works below). The code P0102 is set when the signal from the mass air flow sensor is lower than expected. Often a car may exhibit some driveability symptoms, such as lack of power, surging, hesitation on acceleration, hard starting, pinging (detonation), or rough idle when started cold. Often the codes P0171 or P0174 could also be stored along with the code P0102, as the incorrect air flow signal can cause the engine to run lean. The codes P0171 and P0174 indicate a lean condition. Checking the freeze frame might help in the diagnostic process. The freeze frame is stored in the ECM along with the trouble code. The freeze frame contains some recorded parameters (e.g. vehicle speed, engine temperature, fuel trim) at the moment when the fault was detected. The freeze frame can also be accessed with a scan tool.



What could cause the code P0102
- faulty or contaminated mass airflow sensor
- debris blocking the air flow at the mass air flow sensor
- unmetered air leaking past the MAF sensor (vacuum leaks)
- PCV system vacuum leaks
- restricted or collapsed intake air duct
- dirty or restricted air filter
- restricted air screen before the air filter
- improper application of aftermarket components (e.g. cold intake, modified air filter, etc.)
- wrong air flow sensor installed
- electrical problem with the MAF sensor wiring, connector, power supply or ground.
- problem with ECM
- in some cases other issues with the fuel injection system like a clogged catalytic converter or a faulty manifold absolute pressure sensor (MAP) can also cause the code P0102.

2003 Grand Am Has P0102


It is not an ECM/PCM problem.
P0102 - Mass or Volume Air Flow Circuit Low Input
Possible causes- Faulty mass air flow sensor
- Dirty mass air flow sensor
- Dirty air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor electrical circuit poor connection
- Intake air leaks Tech notes Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner. Reset code and drive vehicle. If the code comes back, it may be necessary to replaced the mass air flow sensor

Car sputters and stops


Hi there:
You might want to change the fuel filter, it may have been clogged by sediment picked up from the tank when it was ran low on fuel.

Also, you could have a bad mass air flow sensor or the snorkel from the mass air flow sensor to the throttle body could be ripped. Both are very common and can cause you vehicle to loose power along with many other drive ability issues.

First look for cracks or rips or anywhere air can enter the engine that is not accounted for by the mass air flow sensor. Next comes the Mass Air Flow (MAF) sensor. This is a very important sensor input to the computer. It uses a hot wire sensing element to measure the amount of air entering the engine. The MAF sensor then outputs an analog voltage signal to the PCM proportional to the intake air mass. The PCM calculates the required fuel injector pulse width in order to provide the desired air/fuel ratio. If the sensor is bad than this air/fuel ratio will be off causing severe performance issues. In extreme cases, I have seen these two problems cause a no start condition. This input can also be used in determining transmission Electronic Pressure Control, shift and torque converter clutch scheduling.

The check engine light may even pop on if the sensor is bad, the snorkel is ripped or a tube has fallen off, this will result in a lean condition. Scanned the computer.

Hope this helps; also keep in mind that your feedback is important and I will appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

As i put my foot on the acc, in all 5 gears, sometimes it judgers like a kangaroo, like its running out of gas


OK number of possibilities here- Im gonna give you the most common ones-

a dirty fuel filter can cause vehicle sputter by blocking the flow of gas from the pump to the engine

a dirty air filter restricts air flow causeing the MAF (mass airflow censor) to report abnormal readings to the ecm (computer) causing the ecm to adjust fuel mix improperly resulting in stutter

bad plugs, wires, or coil - if the engine cant achieve proper spark it will hesitate.

Sounds like you need a tune up- Id check your fuel filter first and go from there, buy plugs before you buy wires, and wires before you buy coils-

Check engine light is on and it sputters when you step on the gas.


It's hard to tell without being able to test drive it but it sounds like it might be the maf sensor (Mass Air Flow) which can cause a backup of fuel or not enough air for the engine to run. Or you may have a collapsed catalytic converter. The catalytic converter burns up any unused fuel from the engine and sometimes the internals of this device can collapse and not allow the exhaust to flow properly. And for your safety, here is a complete list of recalls on your vehicle. If your vehicle is affected by one or more of these recalls then you may qualify for a free repair! http://www.automotive.com/2006/12/lincoln/navigator/recalls/index.html

Is there a way to clean a mass air flow censor , or do you have to buy new. what years and models were the same.any help would be appreciated


You can go to any parts place, they sell mass air flow sensor spray, as far as mass sensor's they look the same but calibraded different.

Codes P0171, and P0174 bLean on a 98 Navigator. Any ideas?


mass air flow sensor is not the problem, I had the exact same problem and have done much research on this. Check the PVC rubber hoses, especially the elbows for cracks. You probably noticed your gas mileage has been horrible too. Hope this helps

I got the codes from auto zone 4 codes came up p1151,p0171,p0174,p1131 all of the codes listed several possibilties and the MAF was listed on them all does the mass air flow censor cause this


it could but most likely not check for a vacuum leak check the hoses to the throttlebody the rubber fittings have a tendancy to get soft and collapse
