OBD II Fault Code

  • OBD II P0468

    OBD-II Code Powertrain Control Module (PCM) failure is defined as a EVAP Purge Flow Sensor Circuit High

    The evaporative control (EVAP) system captures any fuel vapors from the fuel tank and sends them through the vehicle's intake to be burned in the normal combustion process. The EVAP Purge Valve allows the fuel vapors to enter the engine through the intake. When the engine control module (PCM) detects the evap system has flow when it should not, it will set code P0468.

    Common Problems That Trigger the P0468 Code

    • EVAP purge solenoid failure
    • Powertrain Control Module (PCM) failure
    • Wiring issue
