Specs At A Glance

Good To Know

Q: Will I need one sensor or two for my twin-engine Speedster? A: Each 1503 engine uses its own camshaft position sensor, so a twin-engine setup takes two if both are being replaced. Check which engine is throwing the code before ordering.

Q: Can a bad camshaft sensor cause a no-start on one engine? A: Yes, a failed sensor can prevent the ECM from firing that engine while the other runs normally. Swapping in this replacement restores the timing signal.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
