What Does P0027 Code Mean?

    OBD-II Code P0027 is defined as a Exhaust Valve Control Solenoid Circuit Range/Performance

    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.
