Gear Shift Lock Solenoid/Actuator Control Circuit Open
The P092A code indicates that the powertrain control module (PCM) has detected an open circuit in the gear shift lock solenoid/actuator control circuit. This solenoid prevents the shifter from being moved out of Park unless the brake pedal is pressed. An open circuit means there is a break in the electrical path, which can prevent the solenoid from functioning, potentially causing the shifter to be stuck in Park or allowing shifting without brake application.
1. Symptoms You Will Notice
- Unable to shift out of Park
- Shift lever moves without pressing brake pedal
- Brake lights not working
- Check Engine Light illuminated
2. Most Common Causes
- Blown fuse related to the shift lock system
- Faulty brake light switch
- Open or shorted wiring in the solenoid circuit
- Failed shift lock solenoid/actuator
3. Step-by-Step Diagnosis
Step 1: Check for blown fuses in the shift lock circuit and replace if necessary.
Step 2: Test the brake light switch operation; replace if faulty.
Step 3: Inspect wiring and connectors for damage, corrosion, or loose connections.
Step 4: Test the shift lock solenoid resistance and power/ground supply; replace solenoid if out of spec.
