    What Does p0245 Mean?

    OBD-II Code P0245 is defined as a Turbocharger/Supercharger Wastegate Solenoid "A" Low

    The Wastegate solenoid allows unneeded boost generated by the turbo or supercharger to vent the system. The engine control module (PCM) controls the wastegate solenoid. If the PCM cannot control the solenoid, it will set code P0245.The PCM may also disable the turbo or supercharger to prevent further damage to the system.

    What are the common causes of p0245 ?
    • The turbocharger wastegate solenoid is shorted causing a low voltage or high resistance on the solenoid circuit.
    • The wastegate solenoid ground side has a short on the control side causing loss of solenoid control.
    • The solenoid connector has a corrosion buildup or a loose connection that is increasing resistance in the circuit.
    How do you troubleshoot p0245 ?

    You might continue by connecting the scanner to the vehicle diagnostic connector and retrieving all stored codes and freeze frame data. Look for missing ground strap or a rusty ground where the fuel tank is grounded to the frame. Check for damage to the wiring harness connector. If the engine displays a miss and there wasn't a code, determine which cylinder is misfiring. If the exhaust manifold is visible, spay or pour a small amount of water on each cylinder exhaust port. Water will evaporate immediately on good cylinders and slowly on the missing cylinder. If this can't be accomplished pull the plugs and check the condition.
