Good To Know

Q: How do I know if my camshaft position sensor needs replacing? A: Common signs include hard starting, rough running, misfires, or a check engine light on your watercraft. A scan tool can confirm a camshaft position sensor fault code before you order.

Q: Is this sensor difficult to install? A: Installation typically involves removing the old sensor and connecting the plug to the factory harness. Because access varies by model, confirm the mounting location on your machine before starting the job.

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