420664049 Camshaft Position Sensor for Sea-Doo GTI STD 1503 2006 2019

Camshaft Position Sensor for Sea-Doo

This camshaft position sensor, reference 420664049, tells the engine control module where the camshaft sits so fuel injection and ignition timing stay accurate on your watercraft.

Overview

The camshaft position sensor for Sea-Doo reads the rotating camshaft and sends that signal to the engine management system. This camshaft position sensor, cross-referenced to 420664049, helps the ECU time spark and injector pulses correctly. It suits riders repairing a no-start, rough-running, or fault-code condition on their Sea-Doo.

Specs At A Glance

Good To Know

Q: Do I need to program this sensor after install? A: No programming is normally required; the ECU reads the signal once the sensor is mounted and connected. Confirm the fault code clears after starting.

Q: Can a bad camshaft sensor cause a no-start? A: Yes, a failed camshaft position sensor can stop the ECU from timing spark and injection, causing a no-start or extended crank. Replacing it with a 420664049 cross-reference unit addresses that condition.

Good To Know

Q: Is this an original Sea-Doo part? A: No, this is a replacement camshaft position sensor made to fit Sea-Doo models and cross-referenced to 420664049.

Q: Will it fit both the 2006 and 2019 GTI? A: It is listed for the GTI STD 1503 and GTI SE NA 1503 across those model years, so verify your serial number 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.
