EmissionsRelevant
Drive cycleRequired
Limp modeNo
The engine control module learns how far each camshaft of bank 2 is offset from the crankshaft and compares this with a reference. P0009 is set when both camshafts of this bank are shifted in the same direction beyond a threshold. That points to the drive shared by the bank: a stretched primary timing chain, a worn tensioner, an idler gear or a crankshaft reluctor wheel that has slipped. A single faulty camshaft phaser does not set this code, because it affects only one camshaft. Bank 2 exists only on V and boxer engines.
Likely causes
Primary or timing chain stretched
Chain tensioner worn or loose
Timing drive fitted incorrectly after an engine repair
Crankshaft reluctor wheel slipped
Symptoms
- Check engine light on
- Timing chain rattle, especially at cold start
- Loss of power or rough running
- Often stored together with P0016 to P0019
