This code means there's a problem with the part of the car that helps lock the gear shift in place. It's like when a toy's button doesn't work right to keep a part in place.
The P0929 code indicates an issue with the electrical circuit controlling the gear shift lock solenoid or actuator. This solenoid is responsible for ensuring the gear shift is locked or unlocked as needed.
The gear shift lock solenoid is an electronic component that prevents the gear shift from moving out of the 'Park' position unless the brake pedal is pressed. The control circuit for this solenoid is monitored by the vehicle's computer, and if it detects a range or performance issue, it triggers the P0929 code.
• Gear shift lever stuck in 'Park'
• Check Engine Light illuminated
• Inability to shift gears smoothly
• Faulty gear shift lock solenoid
• Damaged wiring or connectors in the circuit
• Malfunctioning transmission control module (TCM)
Solenoid: An electromechanical device that converts electrical energy into mechanical movement.
Actuator: A component responsible for moving or controlling a mechanism or system.
• Check for other related codes.
• Inspect the wiring and connectors for damage.
• Test the gear shift lock solenoid for proper operation.
• Replace the faulty gear shift lock solenoid.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Screwdriver set

Moderate
• Toyota Camry
• Honda Accord
• Ford Fusion
• Regularly inspect and maintain the gear shift components.
• Avoid forcing the gear shift lever.
• Ensure the brake pedal is fully pressed before shifting.
Transmission Control Issue
• Do not force the gear shift lever if it's stuck.
• Have the vehicle inspected by a professional mechanic.
Check with your vehicle manufacturer; powertrain warranties may cover this issue.
This code has been reported in vehicles with electronic shift interlocks, which became more common in the late 1990s.
Moderate – It may prevent the vehicle from being driven if the gear shift is stuck.
Driving with a malfunctioning gear shift lock can be dangerous. Ensure repairs are made promptly.
• Vehicle in 'Park' position
• Brake pedal pressed
The gear shift lock solenoid is typically located near the gear shift lever or within the center console.
Q: Can I drive with a P0929 code?
A: It's not recommended, as you may not be able to shift out of 'Park', making the vehicle undriveable.
Q: How can I reset the P0929 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
