Fuel Gauge Sender: Testing and Inspection
Sensor Ground Connection Check

1. Using an ohmmeter, measure resistance between sensor connector to harness (yellow/red), and ground.
2. Resistance should be approximately 0 ohms.
3. If resistance is correct, check sensor signal.
4. If resistance is incorrect, check for open circuits in wiring between connector (yellow/red), and 30-pole connector on instrument cluster (A4).
