head temperature sensor

Replacement cylinder head temperature sensor. Injection models only. Also fits S&S motors with IST ignition system. The cylinder head temperature sensor is an electronic engine management sensor found on the cylinder head. The cylinder head temperature sensor measures the temperature of the cylinder head. The data is then sent to the ECU to calculate timing and fuel ratio for the engine. Like all sensors, they can fail over time. This may cause long cranking time, decrease in power, acceleration, and fuel economy. If your engine light is on, have the code scanned you may have a faulty cylinder head temp sensor.
