This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with a part of the engine that helps control how the exhaust camshaft moves. It's like a lock that helps the engine parts stay in the right place, and it's not working right.
The P25D5 code indicates that the voltage in the circuit controlling the exhaust camshaft actuator park lock for bank 2 is higher than expected.
The exhaust camshaft actuator park lock control circuit is responsible for managing the position of the exhaust camshaft. A 'high' circuit condition suggests that the voltage level is above the normal operating range, which could be due to a short circuit or a fault in the actuator or wiring.
• Check engine light is on
• Poor engine performance
• Engine misfires or runs rough
• Faulty exhaust camshaft actuator
• Wiring issues such as short circuits
• Faulty PCM (Powertrain Control Module)
Camshaft: A shaft with cams that rotates to move the engine's valves.
Actuator: A device that moves or controls a mechanism or system.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the exhaust camshaft actuator for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the exhaust camshaft actuator if faulty.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Socket set
$150 - $500
Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular maintenance and inspection of engine components
• Ensure proper oil levels and quality
• Address any engine warning lights promptly
Sensor Issue
• Do not ignore the check engine light.
• Seek professional diagnosis if unsure.
• Avoid driving long distances until resolved.
Check with the vehicle manufacturer for warranty coverage on engine components.
This code has been associated with vehicles that have issues with camshaft actuator circuits, particularly in models with advanced engine management systems.
Moderate – While the vehicle may still be drivable, it should be addressed soon to prevent further engine issues.
Driving with a malfunctioning engine component can lead to increased emissions and potential safety risks.
• Engine at operating temperature
• Vehicle in park or neutral
The exhaust camshaft actuator is typically located near the top of the engine, on the side of bank 2.
Q: Can I drive my car with a P25D5 code?
A: It's not recommended to drive for long periods with this code, as it can lead to more serious engine issues.
Q: How can I clear the P25D5 code?
A: After repairs, the code can be cleared with an OBD-II scanner.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
