Gear Shift Lock Solenoid Circuit High Voltage
The P092D code indicates that the powertrain control module (PCM) has detected a high voltage condition in the gear shift lock solenoid/actuator control circuit. 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, which can disable the shift interlock system.
1. Symptoms You Will Notice
- Unable to shift out of Park
- Shift lever stuck in Park even with brake pedal pressed
- Check Engine Light illuminated
- Brake lights may not function properly
2. Most Common Causes
- Faulty shift lock solenoid 'B' with open internal windings
- Short circuit to voltage in the control circuit wiring
- Corroded, bent, or loose electrical connections at the solenoid connector
- Open or high-resistance wiring in the control circuit
- Internal failure of the control module (PCM/BCM) that drives the actuator
3. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Inspect the shift lock solenoid wiring and connector for damage, corrosion, or shorts.
Step 3: Test the solenoid resistance with a multimeter; compare to manufacturer specs.
Step 4: Check the brake pedal position sensor and brake light switch for proper operation.
Step 5: Clear codes and test drive to see if the code returns.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe because you may be unable to shift out of Park, leaving you stranded. Additionally, the brake lights may not work, increasing the risk of rear-end collisions.
How much does it cost to fix?▼
The cost typically ranges from $50 to $150 for parts and labor, depending on whether the solenoid or wiring needs replacement.
5. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
