Specification & Application 

8980237170 is engine water temperature (ECT) sensor used on Isuzu 4HK1, 6HK1, 4JJ1 diesel engines .The sensor with 3 pins. It is a negative temperature coefficient (NTC) thermistor that measures coolant temperature and transmits a voltage signal to both the Engine Control

Module (ECM) for fuel injection and emission control, and the operator instrument panel for the temperature gauge. It is widely fitted in Hitachi, JCB, John Deere, and Case excavators and equipment powered by these Isuzu engines.

Work Guidance

The ECM monitors the ECT signal circuit for voltage plausibility. Because the water temperature sensor is an NTC thermistor, high resistance (cold) produces high signal voltage, and low resistance (hot) produces low signal voltage.

• P0117 (Flash Code 23) ECT Sensor Circuit Low Input ECM detects signal voltage < 0.1 V for 3 seconds — indicates short to ground or a failed sensor with abnormally low resistance
• P0118 (Flash Code 23) ECT Sensor Circuit High Input ECM detects signal voltage > 4.85 V for 3 seconds — indicates open circuit, short to voltage, or a sensor with abnormally high resistance
• P1115 ECT Sensor Circuit Intermittent High Voltage Intermittent open or high-resistance condition in the sensor or harness; can cause erratic temperature readings
