DIAGNOSTIC TROUBLE CODE PROCEDURES

DIAGNOSIS

Required Special Tools:

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

MB991824: V.C.I.

MB991827: USB Cable

MB991910: Main Harness A

MB998464: Test Harness

STEP 1. Check harness connector B-02 at the right bank
heated oxygen sensor (rear) and harness connector B-10 at
the 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 5.

STEP 2. Check the right bank heated oxygen sensor (rear).

(1)

Disconnect  the  right  bank  heated  oxygen  sensor  (rear)
connector  B-02  and  connect  test  harness  special  tool,
MB998464, to the connector on the right bank heated oxygen
sensor (rear) side.

(2)

Warm  up  the  engine  until  engine  coolant  temperature
reaches 80°C (176°F) or higher.

(3)

Drive at 50 km/h (31 mph) or more for 10 minutes.

(4)

Connect a digital voltage meter between terminal No. 2 (black
clip) and terminal No. 4 (white clip).

(5)

Measure the output voltage of heated oxygen sensor under
the following driving.

a
.

Transaxle: 2nd speed

b
.

Drive with wide open throttle

c
.

Engine: 3,500 r/min or more

Standard value: 0.6 - 1.0 volts

NOTE: 

If the sufficiently high temperature [of

approximate 400°C (752°F) or more] is not reached
although the heated oxygen sensor is normal, the output
voltage would be possibly low although the rich air/fuel
ratio.

Q:Is the voltage between 0.6 and 1.0 volts?

YES:

 Go to Step 3.

NO:

 Replace the right bank heated oxygen sensor (rear).

Then go to Step 5.

STEP 3. Check for harness between the right bank heated
oxygen sensor (rear) connector B-02 and the ECM
connector B-10.

(1)

Disconnect  the  right  bank  heated  oxygen  sensor  (front)
connector B-02 and the ECM connector B-10.

Not continuity.

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 P0137 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.

DIAGNOSTIC TROUBLE CODE PROCEDURES

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 P0137 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.
