Engine Coolant Temperature Gauge Check

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 Ohms
Power supply - Engine coolant temperature gauge: 54 ± 2.7 Ohms
Engine coolant temperature gauge-Ground: 232.9 ± 23 Ohms

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.
