Two camshaft position sensors.
In practice, the Chevy Traverse commonly uses a 3.6-liter V6 DOHC engine that requires one camshaft position sensor for each cylinder head, totaling two sensors. The exact count can vary by year or engine option, so it’s best to verify against your vehicle’s VIN or service documentation for your specific model.
Engine variants and CMP sensor counts
The following summarizes the typical CMP sensor arrangement on the Traverse's common engines.
- 3.6L DOHC V6 (LLT and LGX families): two camshaft position sensors (one on Bank 1, one on Bank 2).
For the vast majority of Traverse models, two CMP sensors are standard, reflecting the dual-cam architecture of the V6 engine.
LLT vs LGX comparison
Both the LLT (older generation) and LGX (current generation) 3.6L V6 engines used in the Traverse employ DOHC with cam sensors on each bank, totaling two CMP sensors. The exact sensor part numbers and locations are similar, and replacement practices are the same for both engines.
Where to locate the camshaft position sensors
Knowing the location helps with diagnosis and replacement. The CMP sensors are positioned at the front of the engine on each cylinder head, facing the timing chain area.
- Bank 1 sensor (typically the passenger-side head): near the timing cover, at the front of the engine.
- Bank 2 sensor (typically the driver-side head): near the timing cover on the opposite head.
Correct identification may require removing components for access in some model years. Consult the service manual for precise locations on your VIN.
Common symptoms of CMP sensor issues
If one CMP sensor begins to fail, you may notice timing-related symptoms or check engine codes. The following are typical warning signs:
- Engine misfires, rough idle, or poor acceleration
- Check engine light or fault codes related to camshaft position
- Difficulty starting or failure to start in some cases
- Irregular idle speed or stalling
If you experience these symptoms, have a professional test the sensors and wiring. CMP sensor failure can mimic other engine problems, so a proper diagnostic is essential.
Summary
In the majority of Chevy Traverse models, there are two camshaft position sensors—one for each bank of the 3.6L V6 DOHC engine. While the two-sensor setup is standard, always confirm the configuration for your exact model year and engine by checking the VIN or service documentation. If you’re diagnosing cam timing issues, inspect the CMP sensors, wiring, and connectors as part of a thorough inspection.
