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 terminal, be careful not to touch the printed board.
Standard value:
Power supply-Ground: 178.9 +/- 18 Ohm
Power supply-Engine coolant temperature gauge: 54 +/- 2.7 Ohm
Engine coolant temperature gauge-Ground: 232.9 +/- 23 Ohm
