Q:Is the harness connector in good condition? YES: Then go to Step 7. NO: Repair it. Then go to Step 8. STEP 7. Replace the fuel tank differential pressure sensor. (1) Replace the fuel tank differential pressure sensor. (2) Carry out test drive with the drive cycle pattern. Refer to (3) Check the diagnostic trouble code (DTC). Q:Is DTC P0452 set? YES: Replace the ECM. When the ECM is replaced, register the ID code. Refer to GROUP 42B, ID Code Registration NO: The inspection is complete.
