MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE> 13B-365 STEP 4. Check the No. 3 cylinder injector resistance at at male connector side. (2) Measure the resistance between terminal No. 6 and No. 8. • Resistance should be between 10.5 and 13.5 ohms. Q: Is the measured resistance between 10.5 and 13.5 ohms? STEP 5. Check the harness connector B-103 at No. 3 YES : Go to Step 6. . Then go to Step 9. STEP 6. Check the No. 3 cylinder injector B-103. 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 the intermediate connector B-21 (terminal No. 6) and the injector Then go to Step 9. NO : Replace the No. 3 cylinder injector.
