420664049 Camshaft Position Sensor for Sea-Doo GTX STD HO 1503 2019

Camshaft Position Sensor for Sea-Doo

This camshaft position sensor for Sea-Doo, OEM cross-reference 420664049, reads camshaft rotation and sends timing data to the engine control module so ignition and fuel delivery stay synchronized.

Overview

This camshaft position sensor for Sea-Doo is a direct-fit replacement for a failed or intermittent original unit on the GTX STD HO 1503 platform. The sensor reports camshaft position and speed to the ECM, which uses that signal to time spark and injector pulses correctly. It suits riders and mechanics servicing a 2019 GTX STD HO 1503 who need reliable starting, smooth idle, and clean acceleration restored.

Good To Know

Q: What are the signs of a failing camshaft position sensor? A: Common symptoms include hard starting, rough idle, misfires, and a stored camshaft code. Replacing the sensor with part 420664049 often clears these issues when the sensor is the root cause.

Q: Does this sensor need any programming after installation? A: No programming is normally required, since the ECM reads the signal directly from the sensor. Clear any stored codes and confirm timing reads correctly after the swap.

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