Good To Know

Q: Does this sensor require any wiring changes to install? A: No, it is designed to connect to the factory throttle sensor harness on the listed models. Verify your exact model and year before purchase.

Q: What causes a throttle sensor to fail on a personal watercraft? A: Moisture exposure, vibration, and normal wear over time can degrade the internal sensing element. Replacing it restores accurate throttle signal to the engine management system.
