Code P0101 2021 Honda CR-V Description

The Mass Air Flow (MAF) sensor is attached to the intake air passage, and it measures the amount of intake air flow. The MAF sensor is a chip type air flow meter. The air flow cools the electrically heated chip that is mounted in the air passage. The Powertrain Control Module (PCM) determines the amount of intake air flow by detecting the frequency. If the MAF sensor input frequency is out of range, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
