Camshaft position sensors are used to help the engine’s computer time ignition and fuel delivery. In the 2012 Chevrolet Equinox, the number of camshaft sensors depends on the engine installed in the vehicle.
In the 2012 Equinox, the four-cylinder version uses a single camshaft position sensor, while the V6 versions use two camshaft position sensors—one for each bank of the engine. This aligns with common GM practice for DOHC engines: a single sensor on the 4-cylinder, and two sensors on V6 configurations.
Engine options and sensor counts
Below is a quick breakdown of camshaft sensor counts by engine option typically found in the 2012 Equinox lineup.
- 2.4L inline-4: 1 camshaft position sensor
- 3.0L/3.6L V6: 2 camshaft position sensors (one on each bank)
These counts reflect factory configurations for the 2012 model year. If your vehicle has a different setup due to modifications or a non-stock engine swap, verify with the service manual or a dealer for your specific VIN.
Placement and function
The camshaft position sensor(s) monitor the position and speed of the camshafts to help the engine computer synchronize ignition timing and fuel delivery with the crankshaft. On the 2.4L, there is typically one sensor on the timing cover; on the V6 variants, sensors are typically mounted on or near each cylinder bank. A faulty CMP sensor can cause starting issues, misfires, or poor engine performance.
Summary
For the 2012 Chevy Equinox, expect one camshaft position sensor with the 2.4L inline-4, and two camshaft position sensors with the V6 engines (3.0L/3.6L). Always confirm with your vehicle’s manual or a trusted repair guide based on your exact engine code and VIN.
