Why does my MAF sensor have a code of p0102?
Potential causes for this trouble code may include: Dirty or contaminated mass air flow sensor MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.) Note that other codes may be present if you have a P0102.
What is the trouble code for a MAF sensor?
Note: Some MAF sensors also incorporate an air temperature sensor, which is another value used by the PCM for optimal engine operation. Closely related MAF circuit trouble codes include P0100, P0101, P0103, and P0104. Photo of a MAF sensor: What are some possible symptoms? Symptoms of a P0102 code may include:
What does the MAF signal on the PCM mean?
The powertrain control module (PCM) uses the MAF sensor signal in order to provide the correct fuel delivery for a wide range of engine speeds and loads. A small quantity of air entering the engine indicates deceleration or idle. A large quantity of air entering the engine indicates an acceleration or high load situation.
What is the code for mass airflow sensor?
P0102 is the general code for a problem with the Mass Airflow (MAF) Sensor having a low voltage output to the Engine Control Unit (ECU).
What does p0102 mean on the MAF sensor?
The Mass Airflow (MAF) sensor measures the amount of air entering the engine. When code P0102 is set, there is a low voltage output to the ECM, PCM, or ECU depending on your car type (check your owner’s manual for your specific car). P0102 Symptoms

What is the code for mass air flow sensor?
This Code’s full read out is: P0101 – Mass Air Flow Sensor Circuit Range/Performance. The engine computer uses the MAF sensor signal to determine how much fuel needs to be injected to meet the proper air-fuel ratio.
Potential causes for this trouble code may include: Dirty or contaminated mass air flow sensor MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.) Note that other codes may be present if you have a P0102.
What are the symptoms of a p0102 low OBD code?
Symptoms of a P0102 code may include: 1 Malfunction indicator lamp (MIL) illumination (a.k.a. check engine light). 2 Rough running engine. 3 Black smoke from tail pipe. 4 Stalling. 5 Engine hard start or stalling after it starts. 6 (more items)
What causes a mass air flow sensor to malfunction?
Potential causes for this trouble code may include: Dirty or contaminated mass air flow sensor Failed MAF sensor Intake air leaks MAF sensor electrical harness or wiring problem (open, shorted, frayed, poor connection, etc.)
