This summary uses the existing diagnostic information shown in full below.
Your car has a system that makes sure it doesn't roll away when parked. This error means there's a problem with the part that locks your car in place.
This code indicates an issue with the electrical circuit that controls the park lock or pawl actuator, which is responsible for locking the transmission when the vehicle is in park.
The P2888 code is triggered when the Powertrain Control Module (PCM) detects an open circuit in the park lock or pawl actuator circuit. This actuator is part of the transmission system and ensures the vehicle remains stationary when parked. An open circuit means there is a break in the electrical pathway, preventing the actuator from functioning properly.
• Vehicle rolls when parked
• Check Engine Light is on
• Inability to shift out of park
• Faulty park lock/pawl actuator
• Damaged wiring or connectors in the actuator circuit
• Blown fuse in the actuator circuit
Actuator: A device that causes a mechanism to operate.
PCM: Powertrain Control Module, the vehicle's computer that controls engine and transmission functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Check the fuse related to the park lock/pawl actuator circuit.
• Replace or repair damaged wiring or connectors.
• Replace the faulty park lock/pawl actuator.
• Replace any blown fuses.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect wiring for wear and tear.
• Ensure connectors are clean and secure.
• Perform routine maintenance checks.
Transmission System Issue
• Do not park on steep inclines until the issue is resolved.
• Use the parking brake as an additional safety measure.
Check if your vehicle's powertrain warranty covers transmission components.
This code has been associated with vehicles that have electronic shift and park systems, becoming more common as these systems are adopted.
High – This issue can lead to the vehicle rolling when parked, posing a safety risk.
Ensure the vehicle is secured with the parking brake to prevent accidental movement.
• Vehicle parked on a flat surface
• Ignition in the 'On' position
The park lock/pawl actuator is typically located within the transmission housing.
Q: Can I drive with a P2888 code?
A: It's not recommended, as your vehicle may not stay securely parked.
Q: Will this code cause transmission damage?
A: While it won't directly damage the transmission, it can lead to safety issues if not addressed.
