STEP 1. Check fuel pump module [fuel level sensor (main)] connector D-24 and fuel level sensor (sub) connector D-25 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
STEP 2. Check the fuel level sensor.
STEP 3. Measure the resistance at fuel pump module [fuel level sensor (main)] connector D-24.
STEP 4. Check the wiring harness between fuel pump module [fuel level sensor (main)] connector D-24 (terminal 1) and ground.
- Check the ground wire for open circuit.
Is the wiring harness between fuel pump module [fuel level sensor (main)] connector D-24 (terminal 1) and ground in good condition?
There is no action to be taken. Repair the wiring harness.
STEP 5. Check combination meter connector C-203 for loose, corroded or damaged terminals, or terminals pushed back in the connector.
STEP 6. Check the wiring harness between fuel pump module [fuel level sensor (main)] connector D-24 (terminal 2) and combination meter connector C-203 (terminal 17 or 18).
STEP 7. Using scan tool MB991958, perform actuator test.
STEP 8. Recheck for diagnostic trouble code.
Check again if the DTC is set in the combination meter.(1) Erase the DTC.
(2) Turn the ignition switch from "LOCK" (OFF) position to "ON" position.
(3) Check if DTC is set.
Is the DTC set?
Replace the combination meter. The procedure is complete.
