420664049 Camshaft Position Sensor for Sea-Doo Spark 60 2Up 900 2021-2026

Camshaft Position Sensor for Sea-Doo Spark 60 2Up 900

This camshaft position sensor for Sea-Doo Spark 60 2Up 900 models (OEM cross-reference 420664049) reads camshaft rotation and sends timing signals to the engine management system so fuel delivery and ignition stay synchronized.

Overview

This camshaft position sensor for Sea-Doo is a direct-fit replacement for the factory unit on 2021-2026 Spark 60 2Up 900 watercraft. The sensor reports camshaft position and speed to the ECU, which uses that data to time spark and fuel injection correctly. It suits riders replacing a failed or intermittent sensor and shops servicing Rotax 900 ACE powered Spark models.

Specs At A Glance

Good To Know

Q: How do I know if my camshaft position sensor has failed? A: Common signs include a no-start condition, rough idle, misfires, or a check engine light with a camshaft sensor code. Confirming the fault with a scan tool before replacing avoids unnecessary parts swaps.

Q: Does this sensor need programming after installation? A: No programming is typically required because the sensor simply reports camshaft position to the ECU. A quick test ride and scan tool check confirm the signal reads correctly.

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