STEP 8. Check harness connector B-32 at intermediate
connector for damage.
Q: Is the harness connector in good condition?
YES : Go to Step 9.
NO : Repair or replace it. Refer to GROUP 00E, Harness
. Then go to Step 17.
STEP 9. Check the right bank injector resistance at
intermediate connector B-32.
(1) Disconnect the intermediate connector B-32.
(2) Measure the resistance between each male connector side
terminal.
a. Measure the resistance between terminal No. 5 and No.
9 at No. 1 cylinder injector.
b. Measure the resistance between terminal No. 9 and No.
10 at No.3 cylinder injector.
c. Measure the resistance between terminal No. 4 and No.
9 at No. 5 cylinder injector.
• 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 12.
NO : Go to Step 10.

STEP 10. Check harness connector B-03, B-04, B-01 at
right bank injector for damage.
Q: Is the harness connector in good condition?
YES : Go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness
. Then go to Step 17.
STEP 11. Check the right bank injector.
(1) Remove the intake manifold.
(2) Disconnect the right bank injector connector.
(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
of harness damage. Then go to Step 17.
NO : Replace the injector. Then go to Step 17.

STEP 13. Check for harness damage between right bank
injector connector and PCM connector.
a. Check the harness wire between injector connector B-01
(terminal No. 2) and PCM connector B-23 (terminal No.
153) at No. 1 cylinder injector.
b. Check the harness wire between injector connector B-03
(terminal No. 2) and PCM connector B-23 (terminal No.
140) at No. 3 cylinder injector.
c. Check the harness wire between injector connector B-04
(terminal No. 2) and PCM connector B-23 (terminal No.
133) at No. 5 cylinder injector.
Q: Is the harness wire in good condition?
YES : Go to Step 14.
NO : Repair it. Then go to Step 17.
