NOTE:
On B2200, B2600i and Navajo, remove fuel tank from vehicle for access to fuel gauge sending unit.
- Disconnect fuel gauge sending unit connector. Connect ohmmeter between sending unit harness connector terminals.
- Check resistance readings at indicated float positions. See FUEL GAUGE SENDING UNIT RESISTANCE table. If resistance is not as specified, replace fuel gauge sending unit.
