Spectra S10331 Premium Engine Camshaft Position Sensor

The Spectra Premium S10331 is a direct-fit replacement engine camshaft position sensor (cam sensor) engineered to restore precise ignition timing and fuel injection synchronization. The camshaft position sensor communicates with the engine control module (ECM) to identify which cylinder is firing, enabling the ECM to correctly sequence fuel injector pulses and ignition coil firing for optimal engine performance.

Key Features:

• OE-Matched Design: Engineered to stringent tolerances to meet or exceed original equipment specifications for fit, form, and function — no modifications required
