STEP 1. Using scan tool (M.U.T.-IIISE), check data list item 53: Fuel Tank Temperature Sensor.
STEP 2. Check the fuel tank temperature sensor.
STEP 3. Check the sensor supply voltage at fuel pump module sensor harness side connector.
(1) Disconnect the fuel pump module connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal F/TM line and ground.- Voltage should be between 4.5 and 4.9 volts.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the measured voltage between 4.5 and 4.9 volts?
Go to Step 5. Go to Step 4.
STEP 4. Check of open circuit in F/TM line between fuel pump module connector and ECM connector.
STEP 5. Check the continuity at fuel pump module harness side connector.
STEP 6. Using scan tool (M.U.T.-IIISE), check data list item 53: Fuel Tank Temperature Sensor.
STEP 7. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0183 set?
Retry the troubleshooting. The inspection is complete.
