P05CD

Symptoms

• The Check Engine light comes on during a cold start, goes off after the engine warms up.
• Uneven engine operation during cold start on one side (V-shaped)
• Slight reduction in power when the engine is cold
• Increased fuel consumption during the warm-up phase
• Delays when accelerating a cold engine

Causes

• Engine oil viscosity does not meet manufacturer's requirements
• Bank 2 Camshaft A VVT solenoid dirty or worn
• Wear of the phase shifter (VVT clutch) of bank 2
• Low oil pressure is a common cause with both P05CC and P05CD
• Bank 2 Camshaft Position Sensor Malfunction

How to Fix

1. Check the level and condition of the engine oil; if the viscosity does not match, replace the oil with filter
2. Read all codes; the presence of P05CC together with P05CD indicates a system problem (oil, pump)
3. Check Bank 2 VVT Solenoid: Check electrical resistance and mechanical function
4. Wash bank 2 VVT solenoid with a special cleaner; replace if necessary
5. Check oil pressure with a cold and warm engine
6. If the code is persistent only P05CD, check the phase shifter of bank 2 for contamination and wear.
