P0009 Crank/cam sync: reading or operation not right (bank 2)
P0009 means: Crank/cam sync: reading or operation not right (bank 2). The crankshaft and camshaft sensor signals don't line up. Don't drive until the car has been checked. The engine could be damaged. The most common repair costs about €400–800 in Estonia, depending on make and model.
What it means
The crankshaft and camshaft sensor signals don't line up. The computer sees that the engine timing has shifted. There is a signal, but the reading or operation isn't plausible. The cause may be the part itself or a real mechanical fault. Bank 2 is the side of a V engine without cylinder 1.
What you may notice
- Engine light on
- Hard starting or stalling
- Chain rattle on cold start
- Less power
What could be wrong
- 1Timing chain or belt stretched or jumped a tooth · Timing belt or chain replacement €400–800
- 2Weak chain tensioner · Timing chain tensioner replacement €400–800
- 3Faulty crankshaft or camshaft sensor · Crank or cam sensor replacement €90–180
- 4Camshaft phaser stuck · Camshaft adjuster replacement €250–500
Repair difficulty: Hard
What you can check yourself
Listen to a cold start. If the engine rattles for a few seconds, the chain has probably stretched. Don't drive long distances until it's checked. Best left to a workshop. It needs a diagnostic tool and experience.
How we fix it
- We check the sensor signals and chain stretch on the diagnostic tool
- We check the timing marks
- We replace the chain or belt kit, or the sensor if that's the fault
