Sensor - Cam Position LS Gen III

The Sensor - Cam Position LS Gen III is an OEM-specification replacement component engineered for the Chevrolet Performance LS engine family. This sensor monitors camshaft position and reports timing data to the engine control module, making it essential for accurate spark timing, fuel injection sequencing, and overall engine management. Whether you're rebuilding a stock LS powerplant or maintaining a modified engine in your hot rod, truck, or performance vehicle, a reliable cam position sensor ensures repeatable ignition curves and prevents limp-mode operation caused by timing codes.

This OEM Chevrolet Performance sensor operates using a Hall-effect magnetic pickup design, reading the reluctor ring on the camshaft to determine precise valve timing relative to crankshaft position. The LS Gen III application—which spans 2005–2007 sixth-generation engines and some later variants—requires exact voltage output and signal rise time for proper PCM interpretation. The compact 3.1 x 3.05 x 6.3 inch form factor and lightweight 0.21 lb design facilitate direct bolt-on installation without modification. Unlike aftermarket alternatives, genuine Chevrolet Performance sensors meet GM's original calibration tolerances, eliminating drivability issues that can arise from marginal signal quality or variance in magnetic field strength.

Mechanics and engine builders standardly specify this cam position sensor for LS Gen III restorations, stock replacements, and turbo or supercharged builds where ECU feedback accuracy is non-negotiable. Installation takes minutes—the sensor mounts to the engine block or cylinder head with a single fastener and plugs directly into the factory harness. If your LS is throwing P0340, P0341, or P0342 codes, or if you're diagnosing rough idle or hesitation at cruise, this OEM sensor is the first proven step toward stable operation. For reliability and peace of mind on any LS-powered platform, genuine Chevrolet Performance parts deliver the fit and function that tuners and restorationists depend on.
