Walker Products HD Engine Camshaft Position Sensor

The Walker Products HD Engine Camshaft Position Sensor line provides replacement camshaft position (CMP) sensors, also called cam sensors, for heavy-duty and commercial engine applications. The sensor identifies the position of the camshaft and sends that data to the engine control module (ECM). The ECM uses it to time fuel injection and ignition correctly.

Key Features:

• Accurate timing signal: Works with the crankshaft position sensor and the ECM to help keep ignition timing and fuel delivery correct for fuel economy, performance and emissions.
• Hall-effect sensing: As the camshaft rotates, a magnet passes the sensing element. This generates a signal the ECM uses to determine camshaft position.
• Variable valve timing support: Precise camshaft monitoring supports efficient combustion, power output and lower exhaust emissions.
• Built for harsh conditions: Designed to handle temperature swings, vibration, and exposure to oil and other engine fluids.
• Metal and plastic construction: Durable materials help protect the internal sensing element.

A worn or failing camshaft position sensor can cause hard starting, rough running, poor fuel economy, stalling or a check engine light. Replacing it with a Walker Products HD sensor helps restore smooth, reliable engine operation. Select the child item that matches your application.
