MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE> 13B-309 STEP 10. Check the right bank injector. B-104. (3) Measure the resistance between injector side connector terminal No. 1 and No. 2. Standard value: 10.5 − 13.5 ohms [at 20°C (68°F)] Q: Is the measured resistance between 10.5 and 13.5 ohms [at 20 °C (68°F)]? YES : Repair harness wire between injector intermediate connector and right bank injector connector because NO : Replace the injector. Then go to Step 16. STEP 11. Check for harness between the right bank B-104 and the ECM connector B-10. (3) Measure the resistance between the right bank injector connector B-101, B-103, B-104 and the ECM connector a. Connector B-101 (terminal No. 2) and connector B-10 (terminal No. 2) at No. 1 cylinder injector. b. Connector B-103 (terminal No. 2) and connector B-10 (terminal No. 18) at No. 3 cylinder injector. c. Connector B-104 (terminal No. 2) and connector B-10 (terminal No.50) at No. 5 cylinder injector. • Should be less than 2 ohms. Q: Is the harness wire in good condition? YES : Go to Step 12. Connector Inspection . Then go to Step 16. STEP 12. Check for exhaust leaks. YES : Repair it. Then go to Step 16.
