This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the camshaft on one side of the engine is not moving as fast as it should when the engine is cold. It's like the engine is waking up too slowly on one side.
The P054D code indicates that the engine control module (ECM) has detected that the camshaft timing for Bank 2 is over-retarded during a cold start. This means the camshaft is not advancing as expected.
When the engine is started cold, the ECM monitors the camshaft position to ensure it aligns with the expected timing. If the camshaft is too slow to advance, it triggers the P054D code. This can affect engine performance and emissions.
• Check Engine Light is on
• Poor engine performance
• Rough idle
• Increased fuel consumption
• Faulty camshaft position actuator
• Low engine oil pressure
• Dirty or contaminated oil
• Faulty oil control valve (OCV)
• Timing chain or belt issues
Camshaft: A shaft in the engine that controls the opening and closing of the valves.
ECM: Engine Control Module, the computer that manages engine functions.
• Check for other related codes
• Inspect the engine oil level and condition
• Test the camshaft position actuator
• Inspect the timing chain or belt for wear
• Change the engine oil and filter
• Replace the camshaft position actuator
• Repair or replace the oil control valve
• Inspect and repair timing chain or belt
• OBD-II scanner
• Oil pressure gauge
• Wrench set
• Multimeter

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular oil changes
• Use manufacturer-recommended oil
• Routine engine inspections
Engine Performance
• Have the vehicle inspected by a professional
• Avoid hard driving until the issue is resolved
Check with your manufacturer; camshaft issues may be covered under the powertrain warranty.
This code has been reported in vehicles with variable valve timing systems, especially in colder climates where oil viscosity can affect performance.
Moderate – While the car may still run, delaying repairs can lead to more serious engine damage.
Driving with this code can lead to increased emissions and potential engine damage. It is advisable to address the issue promptly.
• Engine must be cold
• Vehicle should be started and run at idle
The camshaft position actuator is typically located on the cylinder head near the camshaft.
Q: Can I drive with a P054D code?
A: It's not recommended to drive for extended periods with this code, as it can lead to further engine damage.
Q: Will the Check Engine Light turn off after repairs?
A: Yes, after repairs and clearing the code with an OBD-II scanner, the light should turn off.
