Cold Start Camshaft Timing Over-Retarded Bank 2
The P054D code indicates that the engine control module (ECM) has detected that the camshaft timing on bank 2 is excessively retarded during cold start conditions. This typically occurs when the variable valve timing (VVT) system fails to advance the camshaft to the correct position for cold starts, often due to a stuck or slow-acting VVT actuator, low oil pressure, or contaminated oil. The condition can cause rough idle, poor cold start performance, and increased emissions.
01. Most Common Causes
- Faulty VVT actuator or solenoid on bank 2
- Low engine oil level or pressure
- Contaminated or degraded engine oil
- Worn timing chain or tensioner
- Faulty camshaft position sensor
02. Symptoms You Will Notice
- Check Engine Light on
- Rough idle or misfire during cold start
- Poor engine performance and hesitation
- Increased fuel consumption
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and freeze frame data to confirm conditions.
Step 2: Check engine oil level and condition; replace if dirty or low.
Step 3: Inspect VVT actuator and solenoid on bank 2 for proper operation using a scan tool to command timing changes.
Step 4: Test camshaft position sensor and wiring for faults.
Step 5: If necessary, perform a mechanical timing check to rule out chain stretch or skipped teeth.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as retarded timing can cause poor performance, increased emissions, and potential engine damage if the underlying issue worsens.
How much does it cost to fix?▼
Repair costs typically range from $150 to $400, depending on whether the VVT actuator, solenoid, or oil system components need replacement.
