    What does P0968 Mean?

    OBD-II Code P0968 is defined as a Pressure Control Solenoid "C" Control Circuit/Open

    The Transmission Fluid Pressure Solenoid allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the electrical circuit to or from this solenoid, the PCM or TCM will set code P0968.

    What are the common causes of P0968 ?
    • Some aftermarket accessories and performance modifications
    • A faulty oxygen sensor. This will set a code in itself, however, a faulty oxygen sensor does not automatically condemn the sensor. The code just means that the sensor signal was not within specifications. An air leak or any of the above will cause an erroneous signal. There is a multitude of O2 codes relating to O2 performance which gives a clue to the problematic area.
    • Defective ECU strategies or components will prevent proper regeneration

    How do you troubleshoot P0968 ?

    The engine system, in conjuction with the engine control module (ECM)/powertrain control module (PCM), activates the P0968 code solenoid valve to control oil pressure to the engine mechanism that is installed in the valve system to switch valve timing between Low and High.If the engine solenoid valve has an open or short circuit, a DTC is stored.
