What is this code for a check engine light P0101
Looks like it’s a Mass Airflow Sensor code.

A reply 7 hours after the post . Which was nice of Carolyn but putting P0101 in Google would provide the answer in seconds.

It’s saying the computer is detecting an unusually high voltage output from the maf sensor. Could be a problematic sensor, or power supply/ground to the sensor, or problem in the wires between the sensor and the computer. For that sensor to work correctly the engine has to be air tight, so vacuum leaks, and especially leaks in any part of the path from the air filter to the throttle body should be inspected for first.
