MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS TSB Revision MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE> 13B-321 STEP 6. Check for harness connector B-115, B-116, B-120 YES : Then go to Step 7. . Then go to Step 13. STEP 7. Check the left bank injector. B-120. (2) Measure the resistance between injector side connector terminal No. 1 and No. 2. • Standard value: 10.5 and 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 : Go to Step 8. STEP 8. Check for harness between the left bank injector B-120 and the ECM connector B-10. (2) Measure the resistance between the left bank injector connector B-115, B-116, B-120 and the ECM connector • Should be less than 2 ohms. a. Connector B-115 (terminal No. 2) and connector B-10 (terminal No. 51) at No. 6 cylinder injector. b. Connector B-116 (terminal No. 2) and connector B-10 (terminal No.19) at No. 4 cylinder injector. c. Connector B-120 (terminal No. 2) and connector B-10 (terminal No. 3) at No. 2 cylinder injector. Q: Is the harness wire in good condition? YES : Go to Step 9. . Then go to Step 13.
