Description
The PAI 350620 is a 2-pin magnetic pickup camshaft position sensor for Caterpillar C-series electronic diesel engines, replacing CAT 191-8304 and superseded part numbers 189-9801 and 194-5340. The sensor monitors camshaft rotation and feeds timing data to the ECM for fuel injection synchronization. Fits C11, C12, C13, C15, and C18 engine families used in Class 8 trucks and Cat off-highway machines.
Signs You Need a New Camshaft Position Sensor
- Engine cranks but won’t start or has extended crank times
- Intermittent stalling or sudden engine shutdown
- Rough idle, misfires, or hesitation under load
- Check engine light with cam-sensor fault codes
- Erratic tachometer readings
