Specs At A Glance

Good To Know

Q: How do I know if my temperature sensor has failed? A: Common signs include a temperature warning that never activates, erratic gauge readings, or an overheat alarm that triggers when the engine is running cool. Testing the sensor's resistance against factory specs confirms whether replacement is needed.

Q: Does this sensor come with a connector or wiring? A: The listing covers the sensor itself as shown in the title and cross-reference. Reuse the existing connector and wiring from your craft during installation.

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