MULTIPORT FUEL INJECTION (MFI) <3.0L>
13B-263
STEP 12. Check for harness damage between right bank
injector connector and ECM connector <M/T> or PCM
connector <A/T>.
a. Check the harness wire between right bank injector connec-
tor B-01 (terminal No. 2) and ECM connector C-51 (terminal
No. 1) <M/T> or PCM connector C-52 (terminal No. 1)
<A/T> when checking No. 1 cylinder.
b. Check the harness wire between right bank injector connec-
tor B-05 (terminal No. 2) and ECM connector C-51 (terminal
No. 24) <M/T> or PCM connector C-52 (terminal No. 24)
<A/T> when checking No. 3 cylinder.
c. Check the harness wire between right bank injector connec-
tor B-26 (terminal No. 2) and ECM connector C-51 (terminal
No. 10) <M/T> or PCM connector C-52 (terminal No. 10)
<A/T> 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 On-vehicle Service
− Fuel Pressure Test.
Q: Is the fuel pressure normal?
YES : Replace the ECM or 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
Diagnostic Function
− OBD-II Drive Cycle − Procedure 6 −
Other Monitor
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0134 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

.
CIRCUIT OPERATION
• Power is supplied from the MFI relay (terminal
No. 4) to the right bank heated oxygen sensor
(front) heater.
• The ECM (terminal No. 4) <M/T> or PCM (termi-
nal No. 4) <A/T> controls continuity to the right
bank heated oxygen sensor (front) heater by
turning the power transistor in the ECM <M/T> or
PCM <A/T> "ON" and "OFF".
.
TECHNICAL DESCRIPTION
• The ECM <M/T> or PCM <A/T> checks whether
the heater current is within a specified range
when the heater is energized.
.
DESCRIPTIONS OF MONITOR METHODS
Right bank heated oxygen sensor heater (front) cur-
rent is out of specified range when engine coolant
temperature is over 20
°C (68°F).
.
MONITOR EXECUTION
Continuous

in memory for the item monitored below)
• Not applicable
Sensor (The sensor below is determined to be
normal)
• Engine coolant temperature sensor
