What This Sensor Helps Address

• Incorrect coolant temperature readings sent to the engine computer
• Cooling fan operation that does not match engine temperature
• Hard starting or rough running caused by inaccurate temperature input
• Check engine light concerns related to coolant temperature sensor performance
• Fuel mixture and drivability issues tied to faulty temperature data

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. EF0178 uses a blade terminal design with a rectangular female connector and no wiring harness included, so the existing vehicle connector must match the sensor. Confirm whether the application is push-in type, push-in twist lock, or located on adapter based on the vehicle listing before ordering.
