Crank/cam position correlation (Bank 1 Sensor B)
What P0017 means
Your car's computer set P0017: Crank/cam position correlation (Bank 1 Sensor B). It belongs to the fuel and air metering group of codes. It is a generic code, so it means the same thing on every make. The check engine light usually comes on once the fault has been seen on two drives in a row. Until then it shows up as a pending code.
Can I keep driving? Get this checked soon. A badly stretched chain can jump time and damage the engine.
Common causes
- Stretched timing chain or worn guides
- Timing belt or chain jumped a tooth
- Faulty cam or crank position sensor
- Variable valve timing solenoid stuck
Fix the cheapest, most likely cause first. Clearing the code without a repair only turns the light off until the fault comes back.
Check it yourself
A rattle from the front of the engine on cold start is a classic timing chain sign. Check the oil level and condition too.
