Walker Products Engine Camshaft Position Sensor 235-1621 for 2004-2005 Chevrolet/GMC 6.6L

The Walker Products Engine Camshaft Position Sensor (part number 235-1621) is a direct-fit replacement for 2004-2005 Chevrolet and GMC vehicles with 6.6L engines. Identifies position of the Camshaft to the ignition control module (ICM), engine control module (ECM) or powertrain control module (PCM).

Features:

• As the camshaft rotates, the magnet moves past the Hall-effect sensor, generating a voltage signal that is then sent to the engine control module, which uses it to determine the correct timing of the fuel injection and ignition systems.
• Cam sensors are designed to withstand the harsh conditions within an engine compartment, including temperature fluctuations, vibrations, and exposure to engine fluids.
• Facilitates precise variable valve timing, optimizing efficiency, power, and emissions. Accurate tracking of camshaft position enhances combustion cycles, enabling better engine performance and reduced environmental impact.
• Delivers highly accurate timing signals to the engine control module, ensuring optimal engine performance.
• Camshaft Position Sensor work together with the crankshaft position sensor and the vehicle’s ECU to ensure that both ignition timing and fuel supply are correct for peak fuel economy, performance, and emissions.
