Good To Know

Q: How do I know if my throttle sensor has failed? A: Common signs include erratic idle, delayed throttle response, or a fault code stored in the ECU. Diagnosing with a scan tool before ordering helps confirm the sensor is the cause.

Q: Is this an original Sea-Doo part? A: This is an aftermarket throttle sensor built to replace OEM part number 278002284. It is not manufactured by Sea-Doo.

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