P0011 — Intake camshaft on Bank 1 is advanced beyond the commanded angle — VVT actuator over-shot the target position. Symptoms: hard cold start, drops in power, poor idle quality

What it means

Common causes

• Clogged oil control screen — VVT solenoid isn't getting enough oil pressure
• Worn or seized VVT phaser on the intake cam
• Faulty VVT solenoid (Oil Control Valve)
• Low or thin engine oil past its service interval
• Damaged wiring or corroded connector at the solenoid
• Timing chain jumped a tooth or two on high-mileage engines

How to diagnose

1. 01

   Read all stored and pending codes with an OBD-II adapter — get the full picture, not just the one code.

2. 02

   Capture freeze-frame data (RPM, coolant temperature, engine load) at the exact moment the code triggered.

3. 03

   Inspect the named subsystem with our app's AI explanation — get vehicle-specific causes for your make, model and year.

• P0014 Exhaust camshaft on Bank 1 is over-advanced. Only Bank 1 is monitored on V-engines. Symptoms mirror P0011 but from the exhaust side
• P0012 Intake camshaft on Bank 1 is retarded from the commanded angle — VVT can't reach full advance. Symptoms: sluggish throttle response, rough idle, occasional stall on cold start
• P0013 Open or short in the exhaust VVT actuator solenoid circuit on Bank 1. Engine can't control exhaust cam phasing
• P0015 Exhaust camshaft on Bank 1 is retarded from commanded angle. Typical after significant mileage or long oil change intervals
• P0016 Correlation between crankshaft and intake camshaft on Bank 1 is out of spec. ECM sees the two sensors reporting mismatched positions — timing is physically off
• P0017 Correlation between crankshaft and exhaust camshaft on Bank 1 is out of spec. The two sensors disagree beyond the accepted window
