Temperature Sensor (Gauge): Testing and Inspection

Engine Coolant Temperature (ECT) Sender Gauge Inspection
Warm up sender gauge. Thus make sure its resistance is decreased with increase of its temperature.




ECT Sender gauge specification
136 - 126 Ohm at 50 degree C (122 degree F)
16.4 - 19.4 Ohm at 120 degree C (248 degree F)
