P05CE
Cold Start B Camshaft Position Timing Performance Bank 1
P05CE is an OBD-II diagnostic trouble code meaning: Cold Start B Camshaft Position Timing Performance Bank 1. Common causes: inappropriate engine oil viscosity (too high for low temperatures), bank 1 exhaust shaft vvt solenoid contaminated or failure. Estimated repair cost: $33–389.
Symptoms
- Check Engine Light Is On During Cold Start
- Unstable engine operation and cold emissions
- Increased fuel consumption during warm-up period
- Delayed warm-up of the catalytic converter
- Increased emissions in the first minutes of engine operation
Causes
- Inappropriate engine oil viscosity (too high for low temperatures)
- Bank 1 Exhaust Shaft VVT Solenoid Contaminated or Failure
- Bank 1 exhaust camshaft phase shifter wear
- Insufficient oil pressure during cold start
- Bank 1 Exhaust Camshaft Position Sensor Malfunction
How to Fix
- Check the type and condition of the engine oil; replace with one that complies with the manufacturer's recommendations
- Read frozen frame codes and data; compare with codes P05CC (intake bank 1) - if both are present, a systemic cause is possible
- Find Bank 1 Exhaust Camshaft VVT Solenoid from Engine Diagram
- Check the electrical resistance of the solenoid (typically 7–12 ohms); wash or replace if abnormal
- Check the oil pressure in the VVT system during a cold start
- When saving the code after flushing the solenoid, check the condition of the exhaust shaft phase shifter
