2021年7月9日 · The Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine. See the diagram. The mass air flow sensor measures the amount of air entering the engine or the air flow.

MAF SEN/CIRCUIT-B1 (Mass or volume air Flow ″A″ circuit range/ performance) A high voltage from the sensor is sent to ECM under light load driving condition. A low voltage from the sensor is sent to ECM under heavy load driving condition.

This P0100 diagnostic trouble code (DTC) means that there is a detected problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not performing within the normal expected range of the calculated MAF value.

MAF SEN/CIRCUIT-B1 (Mass or volume air flow “A” circuit high input) An excessively high voltage from the mass air flow sensor is sent to ECM. Harness or connectors (Mass air flow sensor circuit is open or shorted.)

2024年10月18日 · The P0100 code is a diagnostic trouble code that indicates a malfunction in the mass air flow (MAF) circuit. This code typically appears when the vehicle’s engine control module (ECM) detects an issue with the MAF sensor or its wiring. The MAF sensor plays a crucial role in measuring the amount of air entering the engine.

2022年11月5日 · If your 2014 Titan is running rough, showing multiple misfires, and has code P0101, the Mass Air Flow (MAF) sensor may still be involved despite replacement. Double-check the MAF wiring and connections for damage or corrosion. Inspect the air intake system for leaks or blockages that could affect airflow.

2022年12月17日 · The mass air flow sensor is responsible for measuring the amount of air flowing into the engine so that the engine can adjust the fuel mixture accordingly. Without this sensor, the engine will run too rich or too lean, which can lead to decreased performance, increased fuel consumption, and potentially damage the engine.

2020年1月16日 · This diagnostic trouble code (DTC) P0100 means that there is a problem detected with the mass airflow (MAF) sensor or circuit. The PCM detects that the actual frequency signal from the MAF sensor is not operating within the normal expected range of …

The code P0101 means that the signal from the mass air flow sensor (MAF) is out of expected range. The MAF sensor is installed in the engine intake, right after the air filter. it measures the amount of air entering the engine through the throttle valve.

The MIL is ON and DTC P0101 (MAF SEN/CIRCUIT-B1) is stored in the ECM. Confirm the current ECM part number. Reprogram the ECM, if applicable. IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you will be performing.
