P0011: Intake camshaft timing over-advanced (Bank 1)
Fix soonSystem: Timing and valves
What P0011 means
The intake camshaft is turning earlier than the computer expects. This is often linked to oil condition or the variable valve timing system.
Common symptoms
- Rough or unstable idle
- Loss of power
- Worse fuel economy
Common causes
- Low or dirty engine oil
- Faulty variable valve timing solenoid
- Stretched timing chain or belt, or a jumped tooth
- Failing camshaft position sensor
Can I keep driving?
Fix soon. Usually drivable for a short time, but get it checked soon. Ignoring it can waste fuel, raise emissions and lead to more damage.
What to do next
- Write down the code and any symptoms you notice.
- Check the simple things first: the fuel cap, loose connectors and fluid levels where they apply.
- Do not just clear the code. If the light comes back, the cause is still there and needs a proper diagnosis.
- Read live data and freeze frame data with an OBD-II scanner app to see what the car was doing when the code was set.
