Code P0100 2020 Honda CR-V Description

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