Code P0101 or P0102 Mass Air flow Sensor

+

Code P0101 or P0102 Mass Air flow Sensor. The mass air flow (MAF) sensor is an air flow meter that measures the amount of air entering the engine. 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 ...

What causes the P0102 code? The MAF Sensor has low voltage output problems which may have several causes. The source of the problem is the sensor range voltage is lower than normal or required by the ECU to function properly. The most obvious problem is restricted airflow from the air cleaner to the MAF sensor which can be a clogged air filter.

|What is P0102 code meaning? The Mass Air Flow sensor is placed in the stream of intake 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 ().The temperature of the hot film is controlled by the ECM a certain amount. The heat generated by the hot film is reduced as ...

22/11/2016· The wiring harness to the mass air flow sensor (MAF) could have a break in the wires. Disconnect your battery and remove the harness to the MAF and your computer. Use a digital ohm meter and check the wires for resistance. If there is high resistance or the meter reads OL (out of limits), then the wire is broken.

Before buying a MAF sensor, try cleaning it with a specialized spray cleaner, like CRC 05110 made for MAF sensors, as these often get considerable carbon build up from the emission system, especially at idle. The air filter may be very dirty causing the sensor to show low air flow voltage due to air flow restriction. How serious is the P0102 code?
