STEP 7. Check the right bank injector resistance at
intermediate connector B-48.
(1) Disconnect the injector intermediate connector B-48.

(2) Measure the resistance between each injector side

connector terminal.

a. Measure the resistance between terminal No. 1 and No.

2 when measuring No. 1 cylinder.

b. Measure the resistance between terminal No. 1 and No.

3 when measuring No. 3 cylinder.

c. Measure the resistance between terminal No. 1 and No.

4 when measuring No. 5 cylinder.

• Resistance should be between 13 and 16 ohms [at 20°C

(68

°F)].

Q: Is the resistance normal?

YES : Go to Step 10.
NO : Go to Step 8.

STEP 8. Check connector B-01, B-05, B-26 at right bank
injector for damage.
(1) Remove the intake manifold.
(2) Check the right bank injector connector, which deviates

from the standard value at Step 7.

Q: Is the connector in good condition?

YES : Go to Step 9.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 14.

STEP 9. Check the right bank injector.
(1) Check the right bank injector connector, which deviates

from the standard value at Step 7.

(2) Measure the resistance between injector side connector

terminal No. 1 and No. 2.

Standard value: 13

− 16 ohms [at 20°C (68°F)]

Q: Is the resistance between 13 and 16 ohms?

YES : Repair harness wire between injector intermediate

connector and right bank injector connector because
of harness damage. Then go to Step 14.

NO : Replace the injector. Then go to Step 14.

STEP 10. Check connector C-51, C-62 at ECM <M/T> or
connector C-52, C-59 at PCM <A/T> for damage.
Q: Is the connector in good condition?

YES : Go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 11. Check for harness damage between right bank
heated oxygen sensor (front) connector B-27 (terminal No.
4) and ECM connector C-62 (terminal No. 72) <M/T> or PCM
connector C-59 (terminal No. 72) <A/T>.
Q: Is the harness wire in good condition?

YES : Go to Step 12.
NO : Repair it. Then go to Step 14.
