420664049 Camshaft Position Sensor for Sea-Doo GTX 215 1503 2008-2013

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 designed to restore accurate camshaft timing signals on 1503 engine platforms. When the original sensor fails, the ECU loses its reference for valve and ignition timing, which can cause hard starting, misfires, or a no-start condition. Installing this camshaft position sensor for Sea-Doo returns dependable signal output so the engine runs cleanly and reliably.

On-The-Job Use

• Replacing a failed or intermittent original camshaft sensor during engine service
• Fault-code diagnosis for camshaft timing or synchronization errors
• Top-end rebuilds where the sensor is removed and replaced as preventive maintenance
• Restoring reliable cold and hot starting on 1503-powered watercraft

Specs At A Glance

Good To Know

Q: How do I know if my camshaft position sensor has failed? A: Common signs include a check engine code for camshaft timing, hard starting, rough idle, or an engine that cranks but will not run. A diagnostic scan confirming signal loss helps verify the sensor before replacement.

Q: Do I need to reset anything after installing a new sensor? A: Most 1503 platforms relearn camshaft synchronization automatically on the next start cycle. Clearing stored fault codes after installation helps confirm the repair.

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