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 3 Chevrolet models — most commonly on Camaro, Equinox, 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 $1,200 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 Camaro(1 issue)
- Timing Chain Stretch and Correlation Faults on 3.6L LLT/LFX V62010-2015
The 3.6L direct-injected V6 used in fifth-generation Camaro is known for timing chain wear/stretch that can trigger cam/crank correlation faults, rough running, and reduced performance. GM issued service information and special coverage on related 3.6L timing chain concerns across multiple applications, and Camaro owners have documented the same issue in forums and complaints. Poor oil maintenance tends to accelerate wear because chain life is sensitive to lubrication quality and oil change intervals.
Chevrolet Equinox(1 issue)
- 2.4L Ecotec timing/balance chain stretch from tensioner & low oil2010-2017
The 2.4L Ecotec in 2010-2017 Equinox is prone to premature timing-chain and balance-chain stretch, driven primarily by a collapsing chain tensioner and made worse by the engine's known oil-consumption problem (low oil reduces hydraulic pressure to the tensioner). Symptoms are a rattle at cold startup, a check-engine light, and rough running or loss of power. Because the engine is an interference design, a chain that skips timing far enough lets the valves contact the pistons, turning a maintenance item into an engine-destroying failure. GM issued Special Coverage Adjustment 12313D covering premature timing/balance chain wear on certain 2010-2011 2.4L engines.
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 3 models.
What causes P0009 on Chevrolet vehicles?▼
Common causes on Chevrolet: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0009 on a Chevrolet?▼
Repair costs on Chevrolet range from $1,200 to $3,500, depending on the specific model and root cause.
