Good To Know

Q: How do I know if my camshaft position sensor has failed? A: Common signs include hard starting, misfires, or a check engine warning on your 1630-powered Sea-Doo. A diagnostic scan can confirm the cam signal is the source before replacing parts.

Q: Does this sensor require any programming after install? A: No, this is a plug-and-play replacement that reads directly to the factory harness. Clear any stored fault codes after installation and verify timing during a test run.

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