what is the code for mass air flow sensor

Where is the mass airflow sensor located? –

· 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. If the signal from the MAF sensor is lower or higher than expected, the ECM detects a fault and stores the code P0101 in its memory.

Air Mass Sensors · Technipedia · Motorservice

The complete air mass sensor consists of a flow passage (tube), in which the intake air flows past the sensor unit itself. NOTE: Depending on application and vehicle, the air mass sensor is available as a single plug-in module, or fully integrated min a plastic tube. Both versions – with or without tube – are referred to as air mass sensors. Older models have a hot-wire sensor element. Any ...

Does a Mass Airflow Sensor Need to be Programmed After ...

The mass airflow sensor is the component used for detecting the flow of air that is entering the engine of a car. The airflow sensor collects details to determine the amount of needed fuel. After collecting the information, the details will be sent to the Engine Control Unit. The ECU will then deliver the required amount of fuel to the engine. The MAF as it is commonly called is usually placed between the throttle and air …
