What does mass or volume airflow A circuit range performance?
The mass airflow (MAF) sensor is a device that is mounted on the air intake. When the PCM perceives the sensor or its circuit is malfunctioning, OBD-II code P0101 is triggered. Code P0101 means that the MAF sensor relays irrational or out of range readings.
What does code p0101 on mass air flow sensor mean?
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.
When is the mass air flow sensor out of range?
P0101 – Mass Air Flow Sensor Circuit Range/Performance The mass airflow sensor (MAF) measures the amount of air entering the engine. The OBD-II code P0101 is set when the signal from the mass air flow sensor is out of expected range, or in other words, the MAF sensor doesn’t work properly.
Why does my Chevy Tahoe have a code p0101?
In some vehicles (e.g. Chevy Tahoe, Silverado) the code P0101 can be caused by a clogged catalytic converter. To diagnose this issue, exhaust back pressure or the engine vacuum must be checked. Read more about symptoms of a clogged catalytic converter below.
What is the OBD code for mass airflow?
Error Code P0101: Mass Airflow Sensor Circuit Range/Performance Problem. The onboard diagnostic (OBD) code P0101 refers specifically to a Mass or Volume Airflow Circuit Range/Performance Problem. In a vehicle, the mass airflow (MAF) sensor measures the amount of air going into the engine through the intake.
What does the p0101 code on the MAF sensor mean?
Code P0101 means that the MAF sensor relays irrational or out of range readings. What Does the P0101 Code Mean? Diagnostic trouble code (DTC) P0101 code stands for “Mass or Volume Air Flow ‘A’ Circuit Range/Performance.”
When to use check engine light code p0101?
The mass air flow (MAF) sensor measures the amount of air entering the engine. Check engine light code P0101 is set when the measurement of air entering the engine by the mass air flow sensor is outside of the manufacturer’s specified range. The Flat Rate Mechanic is a participant in the Amazon Influencer Program.
