OBD II Fault Code

  • OBD II P0820

    OBD-II Code Powertrain Control Module (PCM) failure is defined as a Gear Lever X-Y Position Sensor Circuit

    The Gear Lever Position Sensor tells the engine computer (PCM) what gear the transmission is in. This sensor is usually built into the Shift Lever. If the Gear Lever Position Sensor gives the PCM an implausible signal, code P0820 is set.

    Common Problems That Trigger the P0820 Code

    • Powertrain Control Module (PCM) failure
    • Shift lever assembly failure
    • Wiring issue
