Keep ignition timing and fuel injection in sync with the Walker Products Engine Camshaft Position Sensor / Crankshaft Position Sensor (MPN 235-1082). It drops in as a direct-fit replacement for a wide range of GM trucks and vans, including the 1994-2001 Chevrolet C1500, 1999-2006 Chevrolet Silverado 1500, 1995-2005 Chevrolet Blazer, 1999-2007 GMC Sierra 1500, 1996-2000 GMC Yukon, 1996-2001 Oldsmobile Bravada, 1997-2000 Isuzu Hombre, and 2000-2005 Workhorse P30 — see the Buyer's Guide tab for the full list of 124 applications.
This sensor identifies the position of the camshaft relative to the ignition control module (ICM), engine control module (ECM), or powertrain control module (PCM), helping the computer keep valve events, fuel delivery, and spark aligned.
- Accurate timing signals: Delivers position data to the engine control module so it can determine the correct fuel-injection and ignition timing.
- Hall-effect or magnetic induction: As the camshaft rotates, the magnet moves past the Hall-effect element, generating a voltage signal the ECM reads.
- Works with the crankshaft sensor: Operates alongside the crankshaft position sensor and the vehicle's ECU to help keep ignition timing and fuel supply correct.
- Built for the engine bay: Designed to withstand temperature fluctuations, vibration, and exposure to engine fluids.
Signs this sensor may need replacing include a stored position-sensor trouble code, hard starting, stalling, or an intermittent misfire; diagnose the cause first, and if a failed sensor is to blame, this replaces it. It is cataloged under both the Engine Camshaft Position Sensor and Engine Crankshaft Position Sensor names.
