MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-113
STEP 6. 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 − Pattern 2
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P0057 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

.
CIRCUIT OPERATION
• Power is supplied from the MFI relay (terminal
No. 2) to the left bank heated oxygen sensor
(rear) heater.
• The ECM (terminal No. 35) controls continuity to
the left bank heated oxygen sensor (rear) heater
by turning the power transistor in the ECM "ON"
and "OFF".
.
BACKGROUND
• The ECM checks whether the heater current is
within a specified range when the heater is ener-
gized.
.
DESCRIPTIONS OF MONITOR METHODS
Left bank heated oxygen sensor heater (rear) current
is out of specified range.
.
MONITOR EXECUTION

DTC SET CONDITION
Logic Flow Chart
.
Check Conditions
• More than 2 seconds have passed since the
engine starting sequence was completed.
• While the left bank heated oxygen sensor (rear)
heater is on.
• Battery positive voltage is between 11 and 16.5
volts.
Judgement Criterion
• The left bank heated oxygen sensor (rear) heater
current has continued to be higher than 10.5
ampere for 2 seconds.
.

TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are: )
• Left bank heated oxygen sensor (rear) heater
failed.
• Left bank heated oxygen sensor (rear) failed.
• ECM failed.
