ZK603150AA00

(1)

Disconnect left bank heated oxygen sensor (rear) connector
B-13 and connect test harness special tool, MB991316, to
the connector on the left bank heated oxygen (rear) sensor
side.

(2)

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

Standard value: 11 - 18 Ω [at 20°C (68°F)]

Q:Is the measured resistance between 11 and 18 ohms [at

20°C (68°F)]?

YES:

 Go to Step 2.

NO:

 Replace the left bank heated oxygen sensor (rear).

Then go to Step 3.

STEP 2. 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 P0058 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 3.

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 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  2  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P0058 set?

YES:

 Retry the troubleshooting.

NO:

 he inspection is complete.

DTC P0069: Abnormal Correlation Between Manifold Absolute Pressure Sensor And
Barometric Pressure Sensor

M11310100169USA0000010000

TECHNICAL DESCRIPTION

｠

The  ECM  detects  abnormality  in  the  sensor  by
comparing the manifold absolute pressure sensor
output with the barometric pressure sensor output.

DESCRIPTIONS OF MONITOR METHODS

The ECM compares the manifold absolute pressure
sensor output with the barometric pressure sensor
output  while  the  engine  control  relay  is  in  "ON"
position after the ignition switch is in "LOCK" (OFF)
position. When the difference exceeds the specified
value between them, the ECM determines whether
the  manifold  absolute  pressure  sensor  /  the
barometric pressure sensor has malfunction or not.

MONITOR EXECUTION
