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 trouble code for mass airflow?
P0102 is a diagnostic trouble code (DTC) for “Mass Airflow (MAF) Circuit Low Voltage Input”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic.
What is the PCM error code for MAF?
Error Code P0103 means the MAF has a higher voltage output to the ECU (Engine Control Unit, an electronic control unit that controls the actuators of the internal combustion engine, ensuring optimal engine performance). Therefore, it is set when the PCM detects the MAF sensor experiencing high voltage output.
How does a mechanic diagnose the p0102 trouble code?
P0102 code will be normally preceded by the Check Engine Light coming on the dashboard display. The engine can run near normal but it may run slightly erratically, have less power and idle inconsistently. The vehicle may have too low of fuel consumption, which could cause internal engine problems. How does a mechanic diagnose the P0102 code?

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 causes the mass airflow ( MAF ) sensor to have low voltage?
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 causes the P0102 code? The MAF Sensor has low voltage output problems which may have several causes.
What does the p0101 sensor on a jeep mean?
P0101 JEEP Meaning The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).
Where is the MAF sensor on a Jeep Patriot?
It’s really cheap and available at any parts store. It sure beats the heck out of having to buy a new sensor. Locate the MAF Sensor – It’ll be in between the air filter and the throttle body. Remove the Sensor- Take care not to damage the wiring harness or the connector pins that receive the harness in the MAF.
