Camshaft Position Sensor for Sea-Doo RXT 1503

This camshaft position sensor replaces OEM part 420664049 for Sea-Doo RXT 1503 models, delivering the timing signal the engine control module needs to manage ignition and fuel delivery.

Overview

This camshaft position sensor is a direct replacement for the OEM 420664049 unit used on Sea-Doo RXT 1503 personal watercraft. The sensor reads camshaft rotation and reports it to the ECU so spark and fuel timing stay accurate across the RPM range. It is built for riders servicing a 2005 to 2006 Sea-Doo RXT 1503 who want a dependable replacement rather than a dealer-only part.

Good To Know

Q: How do I know my camshaft position sensor needs replacing? A: Common signs include hard starting, misfires, rough idle, or a stored fault code for camshaft sensor signal. If the signal drops out, the ECU may lose timing reference and the engine can stall or fail to start.

Q: Does this sensor require programming after installation? A: No programming is needed. It is a plug-and-play replacement for the factory sensor on the listed Sea-Doo RXT 1503 models.

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