The camshaft position sensor reads the position of the camshaft as the engine runs and sends that signal to the engine control module. The module uses it to help time fuel injection and ignition. Signs this sensor may need replacing include a lit check engine light, hard starting or a no-start, stalling, and rough running. These symptoms can have other causes, so diagnose the fault first. If a failed camshaft position sensor is the cause, PC671 is designed to replace it on the listed applications.
