Good To Know

Q: What happens when this sensor fails? A: A failed camshaft position sensor can cause hard starting, rough running, or a no-start condition because the ECU loses timing data. Replacing it restores proper signal to the engine management system.

Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement sensor with OEM cross-reference 420664049. It is not an original Sea-Doo product.

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