Fuel Gauge Inoperative

  1. Turn ignition on. Use Tech 1 scan tester and read any Diagnostic Trouble Codes (DTCs). If Tech 1 displays FUEL SENDER PROBLEM (DTC B0092), go to next step. If Tech 1 does not display FUEL SENDER PROBLEM (DTC B0092), go to step 4).
  2. Turn ignition off. Disconnect modular fuel sender connector, located under vehicle at fuel tank. Connect jumper wire between modular fuel sender harness connector terminals "A" (Purple wire) and ground. Turn ignition on. If fuel gauge reads empty, go to next step. If fuel gauge does not read empty, turn ignition off. Disconnect instrument cluster connector. Check Purple wire for an open circuit or short to ground. Check instrument cluster connector C1, terminal E4 for good terminal contact. See Figure. If all circuits are okay, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION.
  3. Turn ignition off. Check Black/White wire for an open circuit or high resistance. Check modular fuel sender connector for good terminal contact at terminals "A" (Purple wire) and "D" (Black wire). Check modular fuel sender wiring for damage. If all wiring is okay, replace fuel level sensor.
  4. Turn ignition off. Disconnect modular fuel sender connector, located under vehicle at fuel tank. Connect 2 Red wires from Gauge Tester (J-33431) to terminals "A" (Purple wire) and "B" (Black wire). Set tester resistance dials to 40 ohms (empty), then to 250 ohms (full). Cycle ignition switch from OFF to RUN position after each resistance value. If fuel gauge displays "E" at 40 ohms, and "F" at 250 ohms on, go to step 6). If fuel gauge does not display "E" at zero ohms and "F" at 90 ohms for both models, go to next step.
  5. Check Purple or Black/White wiring for a short to ground, open circuit, or high resistance. Check instrument cluster connector C1, terminals F16 and E4 for good terminal contact. See Figure. If all circuits are okay, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION.
  6. If LOW FUEL LED indicator does not light when fuel gauge displays "E", replace instrument cluster. See procedures in INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. If LOW FUEL LED indicator does light when fuel gauge displays "E", go to next step.
  7. Check modular fuel sender connector for good terminal contact at terminals "A" (Purple wire) and "D" (Black wire). Also check modular fuel sender wiring for damage. If all circuits are okay, replace fuel level sensor.
