Code P0107 2021 Honda CR-V Description

The P0107 code on a 2021 Honda CR-V indicates a problem with the Manifold Absolute Pressure (MAP) sensor circuit. The MAP sensor is responsible for monitoring the pressure within the intake manifold and providing this information to the engine control module (ECM) to adjust fuel delivery and ignition timing. When the voltage from the MAP sensor falls below the expected range, as indicated by this code, it can lead to various performance issues in the vehicle.
