How many camshaft position sensors does a 2009 Chevy Traverse have?
Two. The 2009 Chevrolet Traverse uses a pair of camshaft position sensors, one for each bank of its dual overhead cam (DOHC) V6 engine. This setup provides the engine computer with timing data for both camshafts and supports any variable valve timing the engine employs.
In this article we explain why two sensors are standard for this engine family, where they’re located, and what that means for maintenance and diagnostics. The 2009 Traverse typically pairs a 3.6-liter V6 with a DOHC layout that relies on sensors on both camshafts to keep timing accurate across operating conditions.
Locations and access
Where the sensors sit
On the 3.6L DOHC V6 used in the 2009 Traverse, you’ll find one camshaft position sensor on each cylinder head—one on the driver’s side (bank 1) and one on the passenger’s side (bank 2). They connect to the engine wiring harness and are accessible with typical service procedures, though you may need to remove some components (such as engine covers or intake hardware) for full access.
Why two sensors matter
Diagnostics and maintenance implications
The dual CMP sensors provide timing information for both camshafts, which the PCM uses to synchronize fuel injection and ignition and to control any variable valve timing. If a sensor fails or its circuit is compromised, you may see trouble codes such as Camshaft Position Sensor Circuit faults (P0340 and related codes) and experience symptoms like rough idle, misfires, or degraded fuel economy. Because there are two sensors, diagnostics should verify both are functioning and that wiring/connectors to both are sound.
Bottom line
For the 2009 Chevy Traverse, two camshaft position sensors—one on each bank of the DOHC V6—constitute the standard configuration. This dual-sensor setup ensures reliable timing data for ignition, fuel delivery, and any variable valve timing the engine uses. When diagnosing CMP-related issues, inspect and test both sensors and their wiring to identify the root cause.
Summary: The 2009 Chevy Traverse typically has two camshaft position sensors, one per bank of its DOHC 3.6L V6. This arrangement supports precise cam timing data for the PCM, aiding ignition, fuel control, and valve timing. For vehicle-specific access points or torque specs, consult the service manual or a professional technician.
How many camshaft position sensors are there?
The number of camshaft position sensors can vary, but vehicles typically have either one for a single overhead camshaft (SOHC) engine or two for a dual overhead camshaft (DOHC) engine with two camshafts per cylinder bank. More complex engines with variable valve timing (VVT) or V6/V8 configurations may have up to four sensors, with one for each intake and exhaust camshaft.
Factors that determine the number of sensors:
- Engine configuration: A simple single-cam engine will only need one sensor, while an engine with separate intake and exhaust cams will need a sensor for each, totaling two for one cylinder bank.
- Number of cylinder banks: A V-shaped engine, like a V6 or V8, has two banks of cylinders. Each bank has its own camshafts, so a four-sensor setup would be common (two per bank).
- Variable Valve Timing (VVT): Systems that adjust the camshaft timing often require an additional sensor to monitor the position of the intake or exhaust camshafts, particularly on newer vehicles with sequential injection.
- Location: Sensors are typically located at the front or rear of the camshaft area, in the cylinder heads, or on the timing cover.

Where is the crankshaft position sensor on a 2009 Chevy Traverse?
And your crank sensor will be right here behind this shield. So we'll go ahead. And get that popped out of. The. Way i know i got my hands in the way. But kind of tight on space right. Here.
