420664049 Camshaft Position Sensor for Sea-Doo Fish 21-230 1630 2025-2026

Camshaft Position Sensor for Sea-Doo Fish 21-230 1630

The Camshaft Position Sensor, part number 420664049, monitors camshaft rotation and reports timing data to the engine control module so fuel delivery and ignition stay synchronized on Sea-Doo Fish 21-230 1630 machines from 2025-2026.

Overview

This camshaft position sensor serves as a direct replacement for the factory unit on select Sea-Doo Fish 21-230 1630 watercraft. The sensor reads the camshaft tone wheel and sends a precise signal to the ECM, which keeps injection and spark timing accurate across the RPM range. It suits owners performing routine maintenance or replacing a failed sensor that has triggered a fault code or rough running.

Good To Know

Q: How do I know if my camshaft position sensor has failed? A: Common signs include a check engine light, hard starting, rough idle, or a stored camshaft position code. A scan tool can confirm the sensor is not reporting correctly before you replace it.

Q: Is this sensor a direct fit for my machine? A: It is built to replace part number 420664049 on the listed Sea-Doo Fish 21-230 1630 models. Always verify your model year and engine serial number match the application before ordering.

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