MULTIPORT FUEL INJECTION(MFI) DIAGNOSIS
MULTIPORT FUEL INJECTION (MFI) <3.0L>
STEP 8. Check the right bank injector resistance at injector
a. Measure the resistance between terminal 1 and 2 when
measuring No.1 cylinder injector
b. Measure the resistance between terminal 1 and 3 when
measuring No.3 cylinder injector
c. Measure the resistance between terminal 1 and 4 when
measuring No.5 cylinder injector
Resistance should be between 13 and 16 ohm [at 20
Q: Is the resistance normal?
YES : Go to Step 11.
STEP 9. Check the right bank injector.
deviates from the standard value at Step 8.
(3) Measure the resistance between injector side connector
terminal 1 and 2.
Standard value: 13
16 ohm [at 20
Q: Is the resistance standard value?
YES : Go to Step 10.
malfunction symptom is eliminated.
