Auxiliary Tank Sensor Fault Tracing
Fuel lever sensor auxiliary tank, fault tracing T171982-1985
- Remove battery negative lead.
- Unplug connector and measure with an ohmmeter between the white-gray leads.
Resistance should be between 1 ohm, with auxiliary tank empty, and 18 ohm, with auxiliary tank full.
If resistance reads infinity, measure directly on the sensor terminals.
With resistance other than between 1 and 18 ohm, the sensor is faulty and needs changing.

1986-
- Remove battery negative lead.
- Unplug connector and measure with an ohmmeter between the white-gray leads.
Resistance should be between 0 ohm, with auxiliary tank empty, and 60 ohm, with auxiliary tank full.
If resistance reads infinity, measure directly on the sensor terminals.
With resistance other than between 0 and 60 ohm, the sensor is faulty and needs changing.
