DIAGNOSTIC TROUBLE CODE PROCEDURES

OBD-II DRIVE CYCLE PATTERN

Refer to Diagnostic Function - OBD-II Drive Cycle -
Pattern 2 P.13Ab-8.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are: )

Connector damage.

Right bank heated oxygen sensor (front) heater.

Harness damage

ECM failed.

 

DIAGNOSIS

Required Special Tools:

MB991316: Test Harness

STEP 1. Check harness connector B-03 at the right bank
heated oxygen sensor (front) 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 or replace it. Refer to GROUP 00E, Harness

Connector Inspection P.00E-2. Then go to Step 6.

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

(1)

Disconnect  right  bank  heated  oxygen  sensor  (front)
connector  B-03  and  connect  test  harness  special  tool,
MB991316, to the connector on the right bank heated oxygen
(front) sensor side.

(2)

Measure  the  resistance  between  heated  oxygen  sensor
connector terminal No. 1 (red clip) and terminal No. 3 (blue
clip).

Standard value: 4.5 - 8.0 Ω [at 20°C (68°F)]

Q:Is the measured resistance between 4.5 and 8.0 ohms [at

20°C (68°F)]?

YES:

 Go to Step 3.

NO:

 Replace the right bank heated oxygen sensor (front).

Then go to Step 6.

STEP 3. Measure the power supply voltage at right bank
heated oxygen sensor (front) and harness side connector
B-03.

(1)

Disconnect the connector B-03 and measure at the harness
side.

(2)

Turn the ignition switch to the "ON" position.

(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 (front) connector B-03 (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 (front) connector
B-03 and ECM connector B-10.

(1)

Disconnect  the  right  bank  heated  oxygen  sensor  (front)
connector B-03 and the ECM connector B-10.

(2)

Measure the resistance between the heated oxygen sensor
connector B-03 (terminal No. 3) and the ECM connector B-10
(terminal No. 33).

Should be less than 2 ohms.

(3)

Check  for  the  continuity  between  the  oxygen  sensor
connector B-03 (terminal No. 3) and ground.

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 P0031 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>

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 P0031 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.
