Genuine GM Parts 12734111 - Gen V LT Camshaft Position Sensor Wire

Description

The GM Genuine Parts 12734111 Camshaft Position Sensor Wire Harness is an authentic factory Original Equipment (OE) internal engine pigtail jumper harness engineered specifically for late-model GM Gen V LT-series V8 and V6 engines. Located at the front of the engine block near the timing cover, this specialized wire harness connects the engine's camshaft position sensor (CMP) to the primary engine control harness. Factory wiring leads in this area are exposed to intense thermal cycling, engine vibration, and oil exposure, which can lead to brittle locking tabs, cracked insulation, or intermittent CMP signal faults (such as DTC P0340/P0341). Replacing this jumper wire ensures accurate engine timing signals to the ECM for proper fuel injection synchronization, Variable Valve Timing (VVT) operation, and misfire detection.
