Good To Know

Q: What symptoms point to a bad camshaft position sensor? A: Hard starting, misfiring, or an illuminated check engine light on your 1503 Sea-Doo are common indicators. A scan tool can confirm the cam signal fault before you replace the part.

Q: Is any tuning or programming needed after installation? A: No, this sensor is a direct plug-and-play replacement for the factory harness. Clear stored fault codes and verify timing on a test run after installation.

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