420664049 Camshaft Position Sensor for Sea-Doo GTX STD 155 1503 2017

Camshaft Position Sensor for Sea-Doo GTX STD 155 1503

This camshaft position sensor, referenced under OEM part number 420664049, monitors camshaft rotation and signals the engine control module so fuel delivery and ignition timing stay synchronized on the 1503 engine.

Overview

This camshaft position sensor for Sea-Doo GTX STD 155 1503 delivers the timing signal the ECU depends on for correct fuel injection and spark sequencing. It is a direct replacement part for the 2017 model year and carries the OEM cross-reference 420664049. Riders replacing a failed or intermittent sensor can restore clean starting and smooth acceleration.

Specs At A Glance

Good To Know

Q: How do I know the camshaft position sensor needs replacing? A: Common signs include hard starting, rough idle, misfires, or a fault code tied to camshaft timing on the 1503 engine. If the sensor signal drops out, the ECU may not fire the ignition correctly.

Q: Does this sensor require any special calibration after installation? A: No calibration is normally needed; it reads camshaft position mechanically through the trigger wheel. Clear any stored fault codes after fitting and confirm the engine starts cleanly.

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