Help your engine computer keep track of camshaft position with the Standard Ignition Engine Camshaft Position Sensor PC609, a direct-fit replacement sensor for the 2005-2007 Cadillac STS, 2004-2006 Cadillac SRX and 2004-2006 Cadillac XLR with the V8-4.6L engine.
A camshaft position sensor monitors the rotation of the camshaft and sends a signal to the engine control module. The module uses that signal, along with other inputs, to time fuel injection and ignition. When the original sensor fails, the PC609 replaces it on the listed applications.
Signs this part may need replacing: an illuminated check engine light, hard starting or a no-start, stalling, and rough running. These symptoms can have other causes, so diagnose the fault before replacing the sensor. For removal and installation steps, follow the vehicle service information. See the Buyer's Guide tab to confirm the fit for your vehicle.
