420664049 Camshaft Position Sensor for Sea-Doo GTX Wake 1503 2003-2006

Camshaft Position Sensor for Sea-Doo

This camshaft position sensor, referenced under part number 420664049, monitors camshaft rotation and sends timing data to the engine management system so the ECM can control ignition and fuel delivery accurately.

Overview

The camshaft position sensor for Sea-Doo is a direct-fit replacement component for the 1503 engine platform used in the GTX Wake. It reports camshaft position to the ECM so spark and fuel timing stay synchronized. This camshaft position sensor suits riders replacing a failed or intermittent sensor on their 2003 to 2006 Sea-Doo GTX Wake.

Specs At A Glance

Good To Know

Q: Does this sensor require programming after installation? A: No programming is typically needed; the ECM reads the camshaft signal directly once the sensor is installed and connected. Confirm that the connector and mounting points match your existing sensor.

Q: How can I tell if my camshaft position sensor has failed? A: Common signs include hard starting, rough idle, misfires, or a stored fault code related to camshaft signal. A diagnostic scan can confirm whether the sensor is the source before replacement.

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