(3)
Measure the voltage between terminal No. 1 and ground.
⦆
Voltage should be battery positive voltage.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is battery positive voltage (approximately 12 volts)
present?
YES:
Go to Step 4.
NO:
Repair harness wire between the MFI relay connector
A-33X (terminal No. 2) and the right bank heated oxygen
sensor (rear) connector B-02 (terminal No. 1) because of
open circuit or harness damage. Then go to step 6.
STEP 4.Check for open circuit to ground or harness damage
between right bank heated oxygen sensor (rear) connector
B-02 and ECM connector B-10.
(1)
Disconnect the right bank heated oxygen sensor (rear)
connector B-02 and the ECM connector B-10.

Measure the resistance between the heated oxygen sensor
connector B-02 (terminal No. 3) and ECM connector B-10
(terminal No. 49).
⦆
Should be less than 2 ohms.

⦆
Not continuity.
Q:Is the harness wire in good condition?
YES:
Go to Step 5.
NO:
Repair it. Then go to Step 6.
STEP 5. Check the trouble symptoms.
(1)
Carry out a test drive with the drive cycle pattern. Refer to
Diagnostic Function - OBD-II Drive Cycle - Pattern 2 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0037 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
MULTIPORT INJECTION SYSTEM (MFI) <DIAGNOSIS>
13Ab-67
DIAGNOSTIC TROUBLE CODE PROCEDURES
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 6.
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 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 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0037 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 (rear)
heater.
⦆
The ECM (terminal No. 49) controls continuity to the
right bank heated oxygen sensor (rear) heater by
turning the power transistor in the ECM "ON" and
"OFF".
TECHNICAL DESCRIPTION
⦆
The ECM 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 (rear)
current is out of specified range.
MONITOR EXECUTION
