To fix a gas gauge on a 1989 Volvo 740 Turbo, first check the fuse associated with the fuel gauge circuit, as a blown fuse can cause it to malfunction. If the fuse is intact, inspect the fuel sending unit in the tank for corrosion or damage; it may need cleaning or replacement. Additionally, verify the wiring and connectors for any signs of wear or disconnection. If these components are functioning properly, the issue may lie in the gauge itself, which could require repair or replacement.
