Gear Shift Lock Solenoid/Actuator Control Circuit Range/Performance
The P092B code indicates that the powertrain control module (PCM) has detected a range or performance issue 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 fault in this circuit can cause the shifter to be stuck in Park or allow shifting without brake application, posing a safety risk.
1. Symptoms You Will Notice
- Unable to shift out of Park (shifter stuck)
- Shifter moves out of Park without pressing brake pedal
- Brake lights not working or staying on
- Check Engine Light illuminated
2. Most Common Causes
- Faulty shift lock solenoid or solenoid resistance out of specification
- Damaged, corroded, or loose wiring in the solenoid 'B' circuit
- Solenoid connector with bent pins, corrosion, or moisture
- Faulty brake light switch or related input signal
- Issue in the transmission control module (TCM) or body control module (BCM)
- Mechanical obstruction in the shift selector lock mechanism
3. Step-by-Step Diagnosis
Step 1: Scan for codes and verify P092B is present. Check for related codes like P092A or P092C.
Step 2: Inspect brake pedal position switch operation and circuit continuity.
Step 3: Test the gear shift lock solenoid resistance and power/ground at the connector.
Step 4: Check fuses and relays related to the shift lock system.
Step 5: Visually inspect wiring and connectors for damage, corrosion, or loose connections.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
No, it is not safe. The vehicle may shift out of Park unexpectedly or get stuck in Park, increasing the risk of an accident. Have it diagnosed and repaired immediately.
How much does it cost to fix?▼
The typical repair cost ranges from $50 to $150 for parts and labor, depending on the exact cause (e.g., solenoid replacement vs. wiring repair).
