What usually causes it
- A stretched timing chain or belt that has slipped a tooth
- A weak camshaft or crankshaft sensor, the parts that report engine position
- A loose or damaged sensor plug or wire
- A stuck oil control valve or worn timing adjuster
P0017Starts at: Get it checked this week
Engine timing sensors do not agree (bank 1, sensor B)
The computer compares the crankshaft sensor with the second camshaft sensor, which is usually on the exhaust side. They do not match, so the engine timing may be off.
Check this first
Check the oil level with the dipstick. Low oil can keep the timing system from working right.
What to watch for
- The engine stalls or will not start
- A rattle or whine from the front of the engine
- Rough running or a flashing check engine light
Can I keep driving?
We rate P0017 as Get it checked this week. It is not an emergency yet, but it can get worse. If the light starts flashing, stop driving soon.
