Good To Know

Q: How do I know if my camshaft position sensor has failed? A: Common signs include hard starting, rough idle, misfires, or a check engine code stored in the ECU. Replacing the sensor with this unit restores proper timing signal to the engine.

Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement sensor built to match the fit and function of OEM part 420664049. It is not an original Sea-Doo component.

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