P0009Engine Position System Performance Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
