OBD II Fault Code

  • OBD II P281C

    OBD-II Code Transmission may not shift properly is defined as a Pressure Control Solenoid "H" Control Circuit Range/Performance

    The Transmission Control Module (TCM) uses Pressure Control Solenoids to control the hydraulic pressure in the transmission which is needed to apply the various clutch packs in the transmission that provide the different gear ratios needed to efficiently propel the vehicle down the roadways. When the TCM detects a pressure control solenoid is not performing as desired, it will set code P281C.
