Part Number: 716/28800
Component Type: Temperature Sensor (Thermistor)
Application: Engine cooling system / transmission system
Manufacturer: Aftermarket
The 716/28800 temperature sensor is a critical component of the JCB machine monitoring system. It is a thermistor whose electrical resistance changes according to the temperature of the monitored medium. Depending on the machine configuration, the sensor is installed either in the engine block (coolant passage) or in the transmission housing to monitor gearbox oil temperature.
The sensor sends an electrical signal to the dashboard gauge or to the ECU control module, informing the operator when operating temperature is reached or when overheating occurs. This function is essential for protecting both the engine and transmission from severe damage.
Applications:
This is a versatile sensor used in various JCB machines, including:
Function and Fault Diagnosis
Typical symptoms of a faulty temperature sensor include:
⚠️ Safety Warning
A failed temperature sensor is a serious risk to the machine. Lack of overheating warnings may result in engine seizure or burnt clutches and transmission failure. Repair costs for such damage far exceed the cost of replacing the sensor.
