Guide to the 2009-2020 Chevrolet Traverse Camshaft Position Sensor
Learn about the symptoms of a failing camshaft position sensor and how to choose the right replacement for your Traverse.
- The 3.6L V6 engine has four camshaft position sensors; two are easy to access, and two are difficult.
- Error codes P0016, P0017, P0018, and P0019 can indicate a serious timing chain problem, not just a bad sensor.
- Due to high labor costs for replacing the rear sensors, using a high-quality OEM or premium aftermarket part is recommended.
- Symptoms of a failing sensor include a Check Engine Light, stalling, rough idle, and difficulty starting.
Is Your Traverse Stalling or Running Rough?
A failing camshaft position sensor can cause noticeable engine problems. The most common sign is the Check Engine Light illuminating on your dashboard. You might also find that your engine is hard to start, stalls unexpectedly, or runs rough. Some owners experience hesitation during acceleration and worse-than-usual gas mileage. In severe cases, a completely failed sensor can prevent the engine from starting at all.
A Critical Warning: Timing Chain Issues
For the 2009-2020 Traverse with the 3.6L V6, certain error codes can be misleading. Codes like P0008, P0016, P0017, P0018, and P0019 are often related to camshaft and crankshaft correlation. While these codes can point to a failed sensor, they are also common symptoms of a much more serious and well-documented problem: stretched timing chains. 🎬 Watch this video to understand timing chain correlation issues. GM has issued Technical Service Bulletins (TSBs) regarding this issue. Before replacing the sensors for these specific codes, it is crucial to have a professional mechanic diagnose the engine to rule out timing chain failure. An incorrect diagnosis can lead to wasted money on sensors when a major engine repair is needed.
Choosing the Right Aftermarket Sensor
When replacing a camshaft position sensor, you have a choice between Original Equipment (OEM) parts from AC Delco and various aftermarket brands. For critical sensors, many mechanics and experienced owners recommend sticking with the OEM brand to ensure reliability and avoid compatibility issues. However, high-quality aftermarket brands like Delphi, NTK, or Standard Motor Products (SMP) are often considered reliable alternatives. Given that some sensors on the Traverse are difficult to access, using a quality part is important to avoid paying for the same labor twice. Budget-friendly options are available, but they may carry a higher risk of premature failure.
Cost to Replace a Chevrolet Traverse Camshaft Position Sensor
| Item | Estimated Cost |
|---|---|
| New OEM (AC Delco) Sensor | $20 - $50 per sensor |
| New Aftermarket Sensor | $23.51 - $31.63 per sensor |
| Shop Labor | $222 - $325 |
| Total Professional Replacement | $368 - $532 |
Pro Tip: Replace in Pairs?
The 3.6L V6 has four sensors. If one sensor fails, especially on high-mileage vehicles, it's possible the others may fail soon. If you are paying for labor to access the difficult-to-reach rear sensors, it may be cost-effective to replace both the intake and exhaust sensors on that bank at the same time.
Frequently Asked Questions
How many camshaft position sensors does a Traverse have?
The 3.6L V6 engine used in the 2009-2020 Chevrolet Traverse has four camshaft position sensors. There is one intake and one exhaust sensor for each of the two cylinder banks 🎬 See a visual guide to sensor and solenoid locations. (Bank 1 and Bank 2).
Can I replace a camshaft position sensor myself?
Yes, for those with some mechanical skill. The two sensors on the front of the engine (Bank 2) are relatively easy to access. However, the two sensors on the rear bank (Bank 1, near the firewall) are much more difficult to reach and may require removing other components like the engine mount. If a rear sensor has failed, many owners may prefer to have a professional perform the replacement.
🎬 Follow this step-by-step guide to replace the sensors yourself.What are the main error codes for a bad camshaft sensor?
Common codes include P0340, P0341, P0345, and P0346, which point directly to a fault in the camshaft position sensor circuits. However, be cautious with codes like P0016, P0017, P0018, and P0019, as they indicate a correlation issue that could be a stretched timing chain instead of a bad sensor.
Are there any recalls for the camshaft position sensor on the Traverse?
As of now, there are no specific recalls issued by the NHTSA for the camshaft position sensor on the 2009-2020 Chevrolet Traverse. However, there are multiple Technical Service Bulletins (TSBs) related to timing chain issues that produce similar error codes.
