MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE> 13B-241 STEP 6. Measure the right bank injector resistance at connector terminal. a. Measure the resistance between terminal No. 6 and No. 7 when measuring No. 1 cylinder. b. Measure the resistance between terminal No. 6 and No. 8 when measuring No. 3 cylinder. c. Measure the resistance between terminal No. 6 and No. 9 when measuring No. 5 cylinder. • Resistance should be between 10.5 and 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 : Go to Step 9. STEP 7. Check harness connector B-21 at right bank from the standard value at Step 6. Q: Is the harness connector in good condition? YES : Go to Step 8. Inspection P.00E-2 . Then go to Step 14. STEP 8. Check the right bank injector. standard value at Step 6. (2) Measure the resistance between injector side connector terminal No. 1 and No. 2. Standard value: 10.5 − 13.5 Ω [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 the injector intermediate connector and the right bank injector NO : Replace the injector. Then go to Step 14.
