P0011
Camshaft variable timing solenoid failure, Engine oil level is too low, The engine is not timed correctly, The engine oil does not meet the manufacturer's requirements, Variable valve timing actuator failure, Worn timing chain
Causes
- Low engine oil level or low oil pressure
- Engine oil viscosity or spec not meeting manufacturer requirements
- Contaminated or old oil blocking oil passages
- Faulty/blocked oil control valve (VVT solenoid)
- Wiring harness damage, connector corrosion, or poor electrical connection to the solenoid
- Failed variable valve timing (VVT) actuator / cam phaser
Symptoms
- Check Engine Light (MIL) illuminated with P0011 stored
- Engine runs rough at idle or rough during acceleration
- Reduced engine power or hesitation on throttle
- Poor fuel economy
- Unusual engine noises (rattling or ticking) from the timing chain/valvetrain area
- Delayed or hard start in some cases
What to check
- Retrieve freeze frame and full list of stored codes; note conditions when code set
- Check engine oil level and condition (viscosity, contamination) and compare to manufacturer's specification
- Scan live-data: compare commanded camshaft angle vs actual camshaft position and monitor VVT solenoid command and feedback
- Visually inspect VVT solenoid connector, wiring harness, and camshaft position sensor connector for damage or corrosion
- Inspect for oil leaks or blocked oil passages in the VVT system
- Listen for timing chain rattle at cold start (possible wear/tensioner issue)
Signal parameters
- Commanded camshaft angle/target (degrees) vs measured/actual camshaft angle (degrees) from CMP data
- Difference/correlation between camshaft and crankshaft position sensors
- VVT solenoid command: duty cycle (%) or switched on/off command from PCM
- VVT solenoid supply voltage (approx. battery voltage when not switched) and control signal voltage
- Solenoid coil resistance (Ω) and continuity — compare to manufacturer spec
- Engine oil pressure (psi/kPa) or oil pressure sensor voltage
Diagnostic algorithm
- Read and record all DTCs and freeze-frame data. Confirm P0011 is current/repeatable.
- Check engine oil level and condition. If low or degraded, restore correct oil level with correct spec oil and retest; resolving oil issues may clear the code.
- Visually inspect VVT solenoid, camshaft position sensor, connectors and wiring for damage, corrosion, or loose pins. Repair as needed.
- Using a scan tool, monitor commanded vs actual camshaft angle while operating. Note magnitude and conditions when discrepancy occurs.
- Back-probe the VVT solenoid connector. Verify control voltage/duty cycle from PCM and battery feed present. Check coil resistance and compare to spec.
- Command the VVT solenoid ON/OFF using a bi-directional scan tool (actuation test). Listen/observe for movement and verify actual cam angle responds when commanded.
- If solenoid is stuck or does not respond electrically, remove and inspect for contamination. Clean or replace the oil control valve as required.
- If solenoid and wiring test good but cam correlation error persists, inspect timing chain/belt and tensioner for wear or jumped tooth; verify timing marks and perform mechanical timing check.
- Inspect VVT actuator/cam phaser for internal failure; replace if stuck or damaged.
- If cam/crank correlation codes also present, test camshaft and crankshaft position sensors and replace if faulty.
- After repairs, clear codes and perform a test drive / re-check live data to confirm commanded vs actual cam angle returns to within expected limits.
- If fault persists after mechanical and electrical checks, consider PCM update or replacement only after all other causes excluded.
Likely causes
- Low engine oil level or inadequate oil pressure
- Clogged/dirty oil control valve (VVT solenoid) or oil passage
- Faulty VVT solenoid (stuck, intermittently operating, or short/open coil)
- Wiring harness damage or poor connector contact at the solenoid
- Worn/tensioner failure or jumped/stretched timing chain causing incorrect cam/crank correlation
- Failed VVT actuator/cam phaser
