P092D Gear Shift Lock Solenoid/Actuator Control Circuit B High

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modeNo

The module sees a higher voltage on shift lock circuit B than the commanded state allows, such as a short to supply or, with a low-side driver, an open coil. No manufacturer documents this code publicly. The documented counterpart on circuit A is FCA P0931 in recall 16V-249, where a badly crimped BTSI solenoid terminal on 2016 Grand Cherokees set the high fault and kept the lever in Park. GHSP patents show that a shifter may carry a second lock solenoid, so circuit B can be a separate lock. CARB requires circuit fault checks on outputs, with an exemption path for safety-only systems. P092C is the low, P092A the open fault of circuit B; P0931 is the same fault on circuit A.

Likely causes

Circuit B wire shorted to a supply voltage
Poor crimp or loose terminal at the second lock solenoid
Open coil in the second lock solenoid

Symptoms

  • Lever will not release from its locked position
  • Fault appears intermittently with vibration
  • Warning message about the shifter or transmission
