This 5-piece camshaft and crankshaft position sensor set tracks engine timing signals the computer uses to control fuel and ignition, and worn sensors commonly cause rough running, stalling, or a check engine light.

It's built for the 3.0L/3.6L GMC Acadia, Terrain, Chevy Traverse, Impala, and Camaro lineup within the Terrain, Acadia, and Sierra engine family.

Replacing the full sensor set together helps resolve intermittent timing issues in one job rather than chasing individual sensor failures.
