    What Does p0246 Mean?

    The PCM has detected an abnormal reading in the turbocharger wastegate solenoid “A” circuit. Circuit A represents a particular wastegate solenoid (where multiple solenoids are used in sequence). There is no set rule for positioning of wastegate solenoids. Check manufacturer’s specifications for specific solenoid locations.

    What are the common causes of p0246 ?
    • Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
    • Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.
    • Fuel with a large percentage of sulfur will clog the DPF quickly
    How do you troubleshoot p0246 ?
    • Repairs that can solve a faulty wastegate solenoid signal include:
    • Repairing damaged wiring or connections to the wastegate solenoid
    • Replacing the solenoid itself
    • Replacing the ECM (this is rarely required)
