P0009 on Chevrolet
Engine Position System Performance - Bank 2
P0009 on Chevrolet vehicles indicates engine position system performance - bank 2. Au7o has documented this code across 1 Chevrolet model — most commonly on Traverse. This code means the engine control module detected that the position of the camshaft(s) on bank 2 is out of alignment with the crankshaft beyond an acceptable range. The computer compares crankshaft and camshaft position sensor signals to confirm the valve timing is correct; when bank 2 is off, the engine's intake and exhaust valves are not opening and closing at the proper moments. This can cause rough running, reduced power, hard starting, or rattling, and on engines with variable valve timing it often involves the timing components or the phasing system. It generally indicates a mechanical timing problem — such as a stretched chain or jumped timing — on the bank of cylinders not containing cylinder 1. Typical repair costs on Chevrolet range from $1,500 to $3,500, depending on the specific model and root cause.
Common Causes of P0009
- •Stretched or worn timing chain on bank 2
- •Worn timing chain guides or tensioner
- •Faulty camshaft phaser / variable valve timing actuator
- •Stuck or clogged VVT oil control (cam phaser) solenoid
- •Low oil level or dirty oil affecting VVT operation
- •Camshaft or crankshaft position sensor fault
- •Timing chain that has jumped a tooth (skipped timing)
P0009 on Chevrolet by Model
Chevrolet Traverse(1 issue)
- Timing Chain Stretch and Failure (3.6L V6 LLT/LFX)2009-2017
The 3.6L V6 (LLT and LFX variants) in the first-generation Traverse is notorious for premature timing chain stretch. The engine uses three timing chains — one primary and two secondary chains driving the variable valve timing actuators. The chains stretch beyond the tensioner capacity, causing the engine timing to slip. Symptoms progress from a rattle on cold start to a check engine light with camshaft correlation codes. If ignored, the stretched chains can skip teeth, causing catastrophic engine damage. The issue typically manifests between 80,000-120,000 miles.

What does P0009 mean on Chevrolet?▼
P0009 stands for "Engine Position System Performance - Bank 2." This code means the engine control module detected that the position of the camshaft(s) on bank 2 is out of alignment with the crankshaft beyond an acceptable range. The computer compares crankshaft and camshaft position sensor signals to confirm the valve timing is correct; when bank 2 is off, the engine's intake and exhaust valves are not opening and closing at the proper moments. This can cause rough running, reduced power, hard starting, or rattling, and on engines with variable valve timing it often involves the timing components or the phasing system. It generally indicates a mechanical timing problem — such as a stretched chain or jumped timing — on the bank of cylinders not containing cylinder 1. On Chevrolet specifically, this code is documented across 1 model.
What causes P0009 on Chevrolet vehicles?▼
