P005C - Camshaft Profile Control Stuck Off Bank 2
The P005C code indicates that the Engine Control Module (ECM) has detected the camshaft profile control system on Bank 2 is stuck in the off position. This system adjusts camshaft timing for optimal performance and emissions. The ECM monitors the camshaft position sensor and oil control valve; if the expected camshaft movement is not detected, it sets this code. Common causes include a faulty oil control valve, low engine oil, or wiring issues.
1. Most Common Causes
- Faulty or stuck camshaft profile control solenoid/actuator 'B' on Bank 2
- Low engine oil pressure or restricted oil passage to the actuator
- Short, open, or high resistance in the actuator circuit wiring or connectors
- Internal mechanical failure of the variable valve lift (VVL) mechanism
- Incorrect, overly viscous, or degraded engine oil
- Faulty powertrain control module (PCM) - rare
2. Symptoms You Will Notice
- Check Engine Light on
- Reduced engine performance and fuel economy
- Rough idle or hesitation
- Possible engine misfire
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Check engine oil level and condition; top off or change if necessary.
Step 3: Inspect wiring and connectors to the Bank 2 oil control valve for damage or corrosion.
Step 4: Test the oil control valve resistance and operation using a multimeter and scan tool.
Step 5: If valve is faulty, replace it; if wiring is bad, repair as needed.
