Q:Is the harness wire in good condition?
YES:
Go to Step 4.
NO:
Repair it. Refer to GROUP 00E, Harness Connector
Inspection P.00E-2. Then go to Step 5.
STEP 4. Check the trouble symptoms.
(1)
Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 23 P.
13Ab-8
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0157 set?
YES:
Replace the ECM. When the ECM is replaced, register
the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 5.
NO:
It can be assumed that this malfunction is
intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

STEP 5. 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 23 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0157 set?
YES:
Retry the troubleshooting.
NO:
The inspection is complete.

CIRCUIT OPERATION
⦆
A voltage corresponding to the oxygen
concentration in the exhaust gas is sent to the ECM
(terminal No. 40) from the output terminal (terminal
No. 4) of the left bank heated oxygen sensor (rear).
⦆
Terminal No. 2 of the left bank heated oxygen
sensor (rear) is grounded with ECM (terminal No.
41).
⦆
The ECM applies an offset voltage of 0.5 volt to
terminal No. 2 of the left bank heated oxygen sensor
(rear).
TECHNICAL DESCRIPTION
⦆
The output signal of the left bank heated oxygen
sensor (front) is compensated by the output signal
of the left bank heated oxygen sensor (rear).
⦆
The ECM checks for the left bank heated oxygen
sensor (rear) output voltage.
DESCRIPTIONS OF MONITOR METHODS
Left bank heated oxygen sensor (rear) output
voltage is over the specified range.
