Resistance Inspection

Engine Coolant Temperature Gauge:

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
