P0009

Engine Position System Performance Bank 2

Q: Is it safe to drive with P0009?

Not for long — the engine may run rough, misfire, or stall, and if the timing is mechanically off, a chain that jumps can damage valves. Get it diagnosed before driving much.

Q: Can I just clear P0009?

Clearing it won't fix anything — it returns once the ECM re-checks cam-to-crank timing. Fix the timing or sensor fault first.

Camshaft/crankshaft timing Generic OBD-II High

What it means

P0009 means the engine computer has decided the "engine position system" on Bank 2 — how the crankshaft and camshaft line up — isn't performing correctly. It usually points to timing that's slightly off from chain or belt wear, a variable-timing problem, or a cam/crank sensor issue. The engine may run rough, misfire, or start hard.

High

Can I keep driving? Risky — expect rough running or hard starting; if a worn or jumping timing chain is behind it, drive as little as possible to avoid engine damage.

How to diagnose & fix

Work through it in order

Read freeze-frame and check engine oil level and condition.
Inspect the Bank 2 camshaft and crankshaft position sensors and their wiring.
Check the timing chain or belt for stretch or misalignment, and verify the timing marks.
Test the VVT oil control valve operation on that bank.
Repair or replace the faulty part, clear the code, and road-test.
