The evaporative emission (EVAP) leak check module pressure sensor is a sensor used for leak detection of the fuel tank. The limit of the EVAP leak check module pressure sensor output is specified. If the output exceeds that limit, the powertrain control module (PCM) detects a malfunction and stores a DTC.
