OBD II Fault Code

  • OBD II P0027

    Fault Code Definition

    • Exhaust Valve Control Solenoid Circuit Range/Performance

    What does this mean? The Exhaust Valve Control Solenoid uses oil pressure and an electrical solenoid to control the position of the exhaust valve. Newer vehicles are equipped with variable valve timing (VVT). This allows the engine control module (PCM) to adjust the opening and closing of the exhaust valve to improve fuel consumption, while still providing the performance requested by the driver. When the PCM determines there is an issue with the signal from the Exhaust Control Solenoid, the PCM will set code P0027.


    • Decreased engine performance
    • Increased fuel consumption

    Common Problems That Trigger the P0027 Code

    • Engine oil level is too low
    • Exhaust valve control solenoid failure
    • Powertrain Control Module (PCM) failure
    • The engine oil does not meet the manufacturer's requirements
