Engine Coolant Temperature Gauge Check

Engine Coolant Temperature Gauge Check:

1. Remove the power supply tightening screw.
2. Use an ohmmeter to measure the resistance value between the terminals.


CAUTION: When inserting the testing probe into the power supply terminal1 be careful not to touch the printed board.


Standard value:
Power supply-Ground: 178.9 ± 18
Power supply-Engine coolant temperature gauge: 54 ± 2.7
Engine coolant temperature gauge-Ground: 232.9 ± 23
3. If within the standard value, the engine coolant temperature gauge is OK.
If not within the standard value, replace the engine coolant temperature gauge.
