P0009
Fix within a few daysYour engine's computer detects a problem with the engine's timing system on Bank 2, meaning the crankshaft and camshafts are not synchronized correctly.
Code P0009 means your engine's timing system on Bank 2 is out of sync. Common causes: Timing chain stretch (70%), VVT actuator failure (20%). Drivability: Limit driving, fix within a few days. Repair cost: $100-$300 DIY, $1,000-$3,000 professional.

Common Causes of P0009
Parts most likely causing this code, ranked by probability
A stretched or worn timing chain (or belt) on Bank 2 causes the crankshaft and camshafts to fall out of synchronization.
70% of P0009 cases are fixed by replacing the timing chain or related components.
A faulty VVT actuator on Bank 2 prevents the camshaft from adjusting its timing correctly, leading to synchronization errors.
20% of P0009 cases are fixed by replacing a faulty VVT actuator.
Insufficient oil pressure or clogged oil passages prevent the VVT system from operating correctly, causing timing issues.
5% of P0009 cases are fixed by addressing oil pressure or passage issues.
A faulty position sensor sends incorrect data to the engine computer, leading it to believe there is a timing synchronization problem.
3% of P0009 cases are fixed by replacing a faulty position sensor.
A rare internal fault within the engine computer can cause it to misinterpret timing signals or fail to control the VVT system correctly.
2% of P0009 cases are fixed by replacing or reprogramming the ECM.
Check These First (Before Buying Parts)
- Check engine oil level and condition. Ensure it's full and clean. Low or dirty oil can cause VVT system malfunctions.
- Listen for any unusual rattling, ticking, or whining noises from the engine, especially from the front (timing cover area) during startup or idle.
How to Diagnose P0009
- 1Check engine oil level and condition. Low or dirty oil can affect VVT operation.
- 2Listen for rattling or whining noises from the engine, especially on startup, which indicates timing chain wear.
- 3Use an advanced scan tool to monitor camshaft and crankshaft position sensor readings and VVT actuator commanded vs. actual positions.
- 4Inspect wiring and connectors for the camshaft and crankshaft position sensors and VVT actuators for damage or corrosion.
- 5Perform an oil pressure test to ensure adequate pressure for VVT system operation.
- 6If timing chain noise is present, inspect the timing chain for stretch and tensioner operation.
P0009 on Popular Vehicles
Chevrolet Traverse
2009-2017GM's 3.6L V6 engine is highly prone to timing chain stretch, leading to P0009. Regular oil changes with synthetic oil are critical to prevent this.

2010-2016Similar to other GM 3.6L V6 applications, the SRX frequently experiences P0009 due to timing chain wear. VVT actuator issues can also contribute.
70% fixed by replacing timing chain components
Ford F-150
2011-2017Ford's 3.5L EcoBoost engine can also develop P0009, often related to timing chain stretch or VVT phaser issues, sometimes accompanied by a cold start rattle.

Frequently Asked Questions
What does P0009 mean?
P0009 indicates that the engine's computer has detected a problem with the synchronization between the crankshaft and camshafts on engine Bank 2. This means the engine's timing is off.
Can I drive with P0009?
Limit driving, fix within a few days. Driving with P0009 can lead to severe engine damage, especially if the timing chain is stretched. The engine may run poorly, stall, or even fail completely.
Will P0009 clear itself?
No, P0009 will not clear itself. This code indicates a mechanical or electrical fault in the engine's timing system that requires diagnosis and repair. The underlying issue must be fixed for the code to clear.
How do I fix P0009 myself?
Start by checking your engine oil level and condition. If that's not the issue, you'll need an advanced scan tool to monitor sensor data and VVT actuator operation. Replacing camshaft position sensors or VVT actuators is possible for an intermediate DIYer, but timing chain replacement is a complex job best left to professionals.
How much does it cost to fix P0009?
DIY costs range from $100-$300 for sensors or VVT actuators. Professional repair costs are $1,000-$3,000, primarily due to the extensive labor involved in replacing timing chains, which is the most common cause.
P0009 keeps coming back - why?
P0009 often returns if the root cause of the timing issue was not fully addressed. This can happen if only a sensor was replaced when the timing chain was actually stretched, or if low oil pressure issues were not resolved before replacing VVT components.
Will P0009 fail emissions/smog test?
Yes, P0009 will cause your vehicle to fail an emissions or smog test. The Check Engine Light being on automatically fails the test in most jurisdictions, and timing issues directly impact engine efficiency and emissions.
What's the difference between P0009 and P0008?
P0009 indicates a timing system performance issue on Bank 2 of the engine, while P0008 indicates the same issue on Bank 1. Many V6 or V8 engines have two banks, and these codes specify which side has the problem.
P0009 on GM 3.6L V6 engines
P0009 is very common on GM vehicles with the 3.6L V6 engine (e.g., Chevy Traverse, Equinox, Cadillac SRX, GMC Acadia, Buick Enclave). This engine is known for timing chain stretch, especially with extended oil change intervals. Addressing the timing chain is often the solution.
Questions to Ask Your Mechanic
Did you check the actual vs. commanded camshaft positions using a scan tool?
Good answer: Yes, the scan tool shows a significant discrepancy on Bank 2, indicating a timing issue.
What did you find regarding the engine oil pressure and condition?
Good answer: The oil pressure is within specification, and the oil is clean, so it's not an oil-related VVT issue.
Have you inspected the timing chain for stretch or listened for timing chain noise?
Good answer: Yes, I hear a distinct rattle from the timing cover area, which points to a stretched timing chain.

Professional recommended - Timing chain replacement is a highly complex and labor-intensive job requiring specialized tools and significant mechanical expertise. Misalignment can cause severe engine damage.
Cost of Waiting
Ignoring P0009 can lead to catastrophic engine failure. A stretched timing chain can jump a tooth, causing valves to hit pistons, resulting in thousands of dollars in engine damage or requiring a complete engine replacement. A $1,000-$3,000 timing chain repair now prevents a $5,000-$10,000 engine replacement later.
While You're In There...
Fresh, clean oil is critical for VVT system operation and timing chain lubrication. You'll likely drain the oil during timing system work.
Valve covers often need to be removed to access timing components or VVT actuators, making it a good time to replace old, brittle gaskets.
On many engines, the water pump is driven by or located behind the timing chain/belt, making it efficient to replace during timing service.
Tools You'll Need
- OBD-II scan tool (advanced with live data capability)
- Socket set and wrenches
- Torque wrench
- Engine oil pressure gauge
- Timing chain locking tools (vehicle-specific)
- Harmonic balancer puller
- Gasket scraper
- Fluid drain pans
P0009 is a serious code, but it's a known issue on many vehicles. Addressing it promptly prevents much larger engine problems. Once fixed, your engine will run smoothly and reliably again.

Your Next Steps
Step 1: Check your engine oil level and condition. Ensure it's at the correct level and not excessively dirty. Low oil can directly cause VVT system issues.
Step 2: If the oil is good, use an advanced OBD-II scan tool to monitor live data for camshaft and crankshaft position sensors and VVT actuator operation. Look for discrepancies between commanded and actual camshaft positions.
Step 3: If live data points to a timing issue, listen for timing chain noise. If present, prepare for a timing chain replacement. Parts you'll likely need include a complete timing chain kit (chains, guides, tensioners, sprockets), VVT actuators (phasers), and associated gaskets and seals.
