Gear Shift Lock Solenoid/Actuator Control Circuit High Voltage
The P092D code indicates that the powertrain control module (PCM) has detected a high voltage condition in the control circuit of the gear shift lock solenoid or actuator. This solenoid prevents the shifter from moving out of Park unless the brake pedal is pressed. A high voltage reading suggests a short to power, a faulty solenoid, or a wiring issue. This can prevent the shifter from releasing, making the vehicle unable to shift out of Park.
01. Most Common Causes
- Short to power in the shift lock solenoid circuit
- Faulty shift lock solenoid/actuator
- Damaged wiring or connector in the solenoid circuit
- Faulty brake pedal position switch
- PCM or software issue
02. Symptoms You Will Notice
- Unable to shift out of Park
- Brake pedal feels hard or unresponsive
- Check Engine Light illuminated
- Shift lock override button may be needed to move shifter
03. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P092D is present. Check for other related codes.
Step 2: Inspect the shift lock solenoid wiring and connector for damage, corrosion, or shorts to power.
Step 3: Test the shift lock solenoid resistance and compare to specifications (typically 10-30 ohms).
Step 4: Check the brake pedal position switch operation and circuit voltage.
Step 5: If wiring and solenoid are okay, test the PCM output to the solenoid circuit.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The vehicle may be stuck in Park, preventing driving. If you can manually override the shift lock, you may drive cautiously to a repair shop, but the issue should be addressed immediately.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for diagnosis and repair, depending on the cause. Replacing the shift lock solenoid or repairing wiring is usually under $100 in parts, with labor adding $50-$100.
