P0009 on Chevrolet by model: symptoms, diagnosis and fix
Worn (stretched) timing chains on the 3.6L High Feature V6 can set DTCs P0008, P0009, P0016, P0017, P0018 and/or P0019, and GM released timing chain service kits for the repair. Applies to: 2009-2012 Chevrolet Traverse with the 3.6L LLT V6 (GM bulletin 12-06-01-009F also lists other GM High Feature V6 models). GM's bulletin does not list 2013-2017 Traverse models.
Common Symptoms
- Cam/crank correlation DTCs P0008, P0009, P0016, P0017, P0018 or P0019
How to Fix
A technician confirms the codes and chain wear, then installs GM's timing chain service kit. GM's bulletin says idler sprockets, camshaft actuator gears, the crankshaft driven gear and the chain guides should not be replaced for a stretched chain unless a guide's wear surface is worn into the base material; it also calls for a PCV service on 2009-2011 Traverses and the latest Oil Life Monitor calibration. Normal warranty rules apply; this is not a recall or a promise of free repair. For vehicles built before June 5, 2009, the bulletin also requires checking the camshaft saddle-cap design and adding specified thrust washers where absent. The technician checks the complete year-specific parts, seals, PCV work and calibration instructions; a generic timing-kit shopping list is not sufficient.
Sources for this issue (1)
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.
Common Symptoms
- check engine light
- rough idle
- reduced power
- hard starting
- rattle on startup
- poor fuel economy
How to Fix
Scan for correlation codes and compare camshaft actual vs. desired timing data before teardown. If chain stretch is confirmed, the correct repair is replacement of the primary/secondary chains, guides, tensioners, and often phaser-related hardware per service procedure; an oil service and verification of proper oil level/condition are also important. Updating maintenance habits after repair is critical to avoid repeat wear.

GM's high-feature V6 in the Equinox suffers premature timing-chain stretch, distinct from the covered 2.4L chain issue. Worn chains/guides/tensioners throw off cam-to-crank timing, setting P0008/P0009 (engine position performance) and P0016-P0019 (crank/cam correlation). The classic symptom is a rattle or chain-slap on cold start from the front/passenger side of the engine. Long oil-change intervals and low oil accelerate the wear; left unfixed, a chain can jump time or break and bend valves.
Common Symptoms
- Rattle/chain-slap on cold start from front of engine
- Check engine light with timing-correlation codes
- Rough idle, hesitation, loss of power
- Reduced fuel economy
- Possible no-start if timing has jumped
How to Fix
Verify with the correlation codes and a cam-timing check; do not keep driving with active correlation codes. Replace the timing chains, guides, and tensioners as a complete updated kit (both banks on the V6), and change oil on time with the correct spec afterward. This is a labor-intensive repair, commonly $2,000-$3,500.

Frequently asked questions
What does P0009 mean on a 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 it is documented across 3 models: Traverse, Camaro, Equinox.
What are the most common causes of P0009?
The most common causes of P0009 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0009 on a Chevrolet?
Published repair estimates on Chevrolet range from $1,500 to $3,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
