Standard Motor Products PC668 Camshaft Position Sensor

The Standard Motor Products PC668 is a direct-fit replacement camshaft position sensor (CMP sensor) engineered to restore precise engine timing and fuel management performance. As a critical component of the engine management system, the camshaft position sensor continuously monitors camshaft rotation speed and position, relaying this data in real time to the engine control module (ECM).

Key Features:

• OEM-quality replacement designed to meet or exceed original equipment specifications for accurate, reliable operation
• Real-time camshaft monitoring provides the ECM with precise position and rotational speed data, including acceleration and deceleration events
• Advanced internal circuitry protects against electromagnetic interference and voltage spikes for consistent signal output
• Custom magnetic circuit design ensures accurate timing correlation between the target wheel and sensor output
• 100% tested — every unit undergoes environmental and endurance validation before leaving the factory
• Direct plug-in fitment for straightforward, no-modification installation

A properly functioning camshaft position sensor is essential for sequential fuel injection timing, cylinder-specific knock control, and ignition system coordination. A failing sensor can trigger check engine lights, cause rough running, hard starts, or reduced fuel economy. The Standard Motor Products PC668 restores factory-correct engine management performance with a maintenance-free design backed by Standard's industry-leading sensor program coverage.
