Good To Know

Q: Will this sensor work on my 2007 Sea-Doo GTI SE DT 1503? A: It is listed for that model year and engine, and it cross-references OEM 420664049. Confirm your machine's serial number and existing sensor part number before ordering.

Q: Does a camshaft position sensor affect starting and power? A: Yes, a faulty sensor can cause hard starting, misfires, or reduced performance because the engine control module loses its timing reference. Replacing it restores proper ignition and fuel sequencing.

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