Without Tachometer

Fuel Gauge Resistance And Engine Coolant Temperature Gauge Resistance:

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: 218.7 - 267.3 Ohm
Power supply-Fuel gauge: 74.7 - 91.3 Ohm
Fuel gauge-Ground: 144.0 - 176.0 Ohm
