Walker 235-91752 Engine Camshaft Position Sensor - Exhaust

Camshaft Position Sensor for Mercedes-Benz AMG

Walker Full Service Kit camshaft position sensor Part Number 235-91752 is a standard replacement sensor for exhaust-side applications on select Mercedes-Benz AMG models. It provides the camshaft position signal the engine control module uses to coordinate valve timing and fuel delivery for smoother operation and consistent drivability.

Built with a 3-wire blade terminal design, a single oval female connector, and an included mounting bracket, this sensor is specified for direct-fit service on Mercedes-Benz C63 AMG, E63 AMG, CLS63 AMG, and related AMG applications. If you are replacing a failing exhaust camshaft position sensor on a Mercedes-Benz AMG, 235-91752 is built for that repair path.

Product Details

Walker Products engineers this camshaft position sensor to monitor camshaft speed and position with the accuracy needed for modern engine management. Using Hall Effect or magnetic induction sensing technology, the unit sends real-time position data to the ECM so ignition timing and fuel injection can stay synchronized. That helps support stable idle quality, efficient combustion, and lower emissions in properly functioning systems. The Full Service Kit line focuses on service-ready replacement parts for demanding drivetrains, and this sensor follows that approach with a standard replacement fit and OE-style connector layout.

• Rough idle or inconsistent engine speed
• Hard starting or extended crank time
• Reduced fuel efficiency from timing signal errors
• Driveability issues tied to exhaust cam sensor failure

Installation Notes

Confirm the connector shape, terminal count, and exhaust-side location before installation. Inspect the mating connector, wiring, and mounting point for corrosion, oil intrusion, or heat damage before replacing the sensor. Clear diagnostic trouble codes after installation and verify proper signal operation with a scan tool if available.
