(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.

DIAGNOSTIC TROUBLE CODE PROCEDURES
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.

Check Conditions
⦆
Ignition switch is in "LOCK" (OFF) position.
⦆
After two seconds pass from the time when the
engine is stopped.
⦆
Engine coolant temperature is higher than 0°C (32°
F).
Judgement Criterion
⦆
Difference between manifold absolute pressure
sensor output and barometric pressure sensor
output is more than 9 kPa (2.7 in.Hg) for 2 seconds.
OBD-II DRIVE CYCLE PATTERN
None.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are: )
⦆
Manifold absolute pressure sensor failed.
⦆
Barometric pressure sensor failed.
⦆
ECM failed.

To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991958.
(1)
Connect scan tool MB991958 to the data link connector.
(2)
Turn the ignition switch to the "ON" position.
(3)
Set scan tool MB991958, read the DTC.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is the diagnostic trouble code other than P0069 set?
YES:
Refer to, Diagnostic Trouble Code Chart P.13Ab-44.
NO:
Go to Step 2.
STEP 2. Using scan tool MB991958, check data list item 8:
Manifold Absolute Pressure Sensor.
(1)
Turn the ignition switch to the "ON" position.
(2)
Set scan tool MB991958 to the data reading mode for item
8, Manifold Absolute Pressure Sensor.
⦆
When altitude is 0 m (0 foot), 101 kPa (29.8 in.Hg).
⦆
When altitude is 600 m (1,969 feet), 95 kPa (28.1 in.Hg).
⦆
When altitude is 1,200 m (3,937 feet), 88 kPa (26.0 in.Hg).
⦆
When altitude is 1,800 m (5,906 feet), 81 kPa (23.9 in.Hg).
(3)
Start the engine.
⦆
When the engine is idling, 16 - 36 kPa (4.7 - 10.6 in.Hg).
⦆
When the engine is suddenly revved, manifold absolute
pressure varies.
