STEP 7. Measure the right bank injector resistance at
intermediate connector B-44.
(1) Disconnect the injector intermediate connector B-44.
(2) Measure the resistance between each injector side
connector terminal.
a. Measure the resistance between terminal No. 3 and No.
8 when measuring No. 1 cylinder.
b. Measure the resistance between terminal No. 1 and No.
8 when measuring No. 3 cylinder.
c. Measure the resistance between terminal No. 6 and No.
8 when measuring No. 5 cylinder.
• Resistance should be between 13 and 16 ohms [at 20°C
(68
° F)].
Q: Is the measured resistance between 13 and 16 ohms [at
20
°C (68°F)]?
YES : Go to Step 10.
NO : Go to Step 8.
STEP 8. Check connector B-01, B-02, B-03 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
. Then go to Step 13.

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 measured resistance between 13 and 16 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 13.
NO : Replace the injector. Then go to Step 13.
STEP 10. Check connector D-132, D-135 at PCM for
damage.
Q: Is the connector in good condition?
YES : Go to Step 11.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 13.

STEP 11. Check for harness damage between right bank
heated oxygen sensor (front) connector B-07 (terminal No.
4) and PCM connector D-135 (terminal No. 109).
Q: Is the harness wire in good condition?
YES : Go to Step 12.

STEP 12. Check for harness damage between right bank
injector connector and PCM connector.
a. Check the harness wire between right bank injector connec-
tor B-01 (terminal No. 2) and PCM connector D-132 (termi-
nal No. 1) when checking No. 1 cylinder.
b. Check the harness wire between right bank injector connec-
tor B-02 (terminal No. 2) and PCM connector D-132 (termi-
nal No. 14) when checking No. 3 cylinder.
c. Check the harness wire between right bank injector connec-
tor B-03 (terminal No. 2) and PCM connector D-132 (termi-
nal No. 2) when checking No. 5 cylinder.
Q: Is the harness wire in good condition?
YES : Go to Step 13.
NO : Repair it. Then go to Step 14.
STEP 13. Check the fuel pressure.
Refer to GROUP 13A, On-vehicle Service
− Fuel Pressure Test
Q: Is the fuel pressure normal?
YES : Replace the PCM. Then go to Step 14.
NO : Repair it. Then go to Step 14.
STEP 14. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to
GROUP 13A, Procedure 6
− Other Monitor
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0134 set?
YES : Retry the troubleshooting.
