What Does P0009 Mean?
P0009 indicates that the engine position system (crankshaft-to-camshaft correlation) on Bank 2 is not performing within the expected parameters. This is the Bank 2 counterpart to P0008, affecting the opposite bank of cylinders on V-configuration engines. The ECM has detected that the camshaft-to-crankshaft timing relationship has drifted beyond acceptable limits. Symptoms include rough running, reduced power, and potential timing chain noise from the Bank 2 side of the engine.
Common Causes
35%
Stretched or worn timing chain on Bank 2 causing camshaft position deviation from the crankshaft reference
25%
Malfunctioning VVT actuator or cam phaser on Bank 2 not maintaining the commanded camshaft position
15%
Low oil pressure or incorrect oil viscosity affecting the hydraulic VVT system on Bank 2
15%
Faulty Bank 2 camshaft position sensor providing incorrect timing data to the ECM
10%
Bank 2 timing chain jumped teeth due to a worn tensioner, broken guide, or cam sprocket failure
Diagnostic Steps
1
Monitor Bank 2 camshaft position vs. crankshaft position correlation in live data — the offset should be within +/- 2-5 degrees of the ECM target at idle and at 2,500 RPM.
2
Check engine oil level and condition — verify the correct viscosity oil is used and that oil changes are not overdue. Low or degraded oil directly impairs VVT operation.
3
Listen for timing chain rattle from the Bank 2 side of the engine at cold startup — compare noise levels between Bank 1 and Bank 2 to isolate the affected side.
4
Use a bidirectional scan tool to command the Bank 2 VVT solenoid through its full range and monitor camshaft position response. The cam angle should advance and retard smoothly without hesitation.
5
If both P0008 and P0009 are present simultaneously, suspect a common cause: low oil pressure, incorrect oil viscosity, or oil passages blocked by sludge. Perform an oil pressure test at the main gallery.
6
Inspect the Bank 2 camshaft and crankshaft reluctor rings for missing teeth, debris buildup, or excessive runout.

The most common cause of P0009 (Engine Position System Performance - Bank 1) is: Stretched or worn timing chain on Bank 2 causing camshaft position deviation from the crankshaft reference
Typical repair costs for P0009 range from $300 to $2,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Similar to P0008 — the vehicle can typically be driven short distances with reduced performance. However, on interference engines, a jumped timing chain risks piston-to-valve contact and catastrophic engine failure. If chain noise is evident, do not drive the vehicle.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0009 to identify the root cause.
