P0931Gear Shift Lock Solenoid/Actuator Control Circuit A High
- Generic OBD-II code · Powertrain
- How the car detects it
- The control module reads a voltage on shift lock circuit A that is higher than the commanded state allows. FCA documents the code directly: in recall 16V-249 the Jefferson North plant found 2016 Jeep Grand Cherokee (WK) vehicles with active or stored P0931-00 whose selector would not release from Park. The cause was a badly crimped terminal on the BTSI solenoid harness from shifter supplier GHSP; FCA replaced the gear selector and warned that losing the solenoid could leave the lever locked in Park or Neutral. So a poor connection, not only a short to battery, can show up as High. P0930 is the low, P0928 the open fault of circuit A; P092D is the high fault on circuit B.
