CIRCUIT OPERATION
⦆
A voltage corresponding to the oxygen
concentration in the exhaust gas is sent to the ECM
(terminal No. 54) from the output terminal (terminal
No. 4) of the right bank heated oxygen sensor
(front).
⦆
Terminal No. 2 of the right bank heated oxygen
sensor (front) is grounded with ECM (terminal No.
55).
⦆
The ECM applies an off set voltage of 0.5 volt to
terminal No. 2 the right bank heated oxygen sensor
(front).
TECHNICAL DESCRIPTION
⦆
The right bank heated oxygen sensor (front) detects
the concentration of oxygen in the exhaust gas; it
converts those data to voltage, and inputs the
resulting signals to the ECM.
⦆
When the right bank heated oxygen sensor (front)
begins to deteriorate, the heated oxygen sensor
signal response becomes poor.
⦆
The ECM the right bank heated oxygen sensor
(front) output voltage.
DESCRIPTIONS OF MONITOR METHODS
Right bank heated oxygen sensor (front) output
voltage is over specified range.

DIAGNOSTIC TROUBLE CODE PROCEDURES
DIAGNOSIS
STEP 1. Check harness connector B-03 at right bank heated
oxygen sensor (front) and harness connector B-10 at ECM
for damage.
Q:Is the harness connector in good condition?
YES:
Go to Step 2.
NO:
Repair it. Refer to GROUP 00E, Harness Connector
Inspection P.00E-2. Then go to Step 4.
STEP 2. Check for short circuit to power supply between the
right bank oxygen sensor connector B-03 and the ECM
connector B-10.
Q:Is the harness wire in good condition?
YES:
Go to Step 3.
NO:
Repair it. Then go to Step 4.
STEP 3. 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 24 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0132 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 4.
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 4. 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 24 P.
13Ab-8.
(2)
Check the diagnostic trouble code (DTC).
Q:Is DTC P0132 set?
YES:
Retry the troubleshooting.
NO:
The inspection is complete.
