Code P0108 2021 Honda CR-V Description

The Manifold Absolute Pressure (MAP) Sensor measures the pressure or vacuum in the manifold. This measurement is converted into an electrical signal which the Powertrain Control Module (PCM) uses to monitor the engine. The MAP Sensor outputs low signal voltage at high vacuum (throttle valve closed) and high signal voltage at low vacuum (throttle valve wide open). If the signal voltage from the MAP sensor falls below or exceeds a set value for a specified time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
