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)

Start the engine and run at idle.

(3)

Set scan tool MB991958 to the data reading mode for item
AC, Heated Oxygen Sensor Bank 1, Sensor 1 (right front).

｠

Warm up the engine. When the engine is revved, the output
voltage should measure 0.6 to 1.0 volt.

｠

Warm up the engine. When the engine is idling, the output
voltage should repeat 0.4 volt or less and 0.6 to 1.0 volt
alternately.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the sensor operating properly?

YES:

 Go to Step 2.

NO:

 Replace it. Then go to Step 3.

STEP 2. 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 P2195 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  23  P.
13Ab-8.

(2)

Check the diagnostic trouble code (DTC).

Q:Is DTC P2195 set?

YES:

 Retry the troubleshooting.

NO:

 The inspection is complete.

DTC P2197: Heated Oxygen Sensor Inactive (bank 2, sensor 1)

M11310100269USA0000010000

TECHNICAL DESCRIPTION

｠

The ECM effects air/fuel ratio feedback control in
accordance  with  the  signals  from  the  left  bank
heater oxygen sensor (front).

｠

If  the  left  bank  heated  oxygen  sensor  (front)  has
deteriorated,  corrections  will  be  made  by  the  left
bank heated oxygen sensor (rear).

｠

DTC P2197 becomes stored in memory if a failure
is detected in the left bank heated oxygen sensor
(front).

DESCRIPTIONS OF MONITOR METHODS

Left  bank  heated  oxygen  sensor  (front)  output
voltage does not cross lean/rich criteria (about 0.5
volt) within specified period.

MONITOR EXECUTION

Continuous

MONITOR EXECUTION CONDITIONS (Other
monitor and Sensor)

Other Monitor (There is no temporary DTC stored in
memory for the item monitored below)

｠

Heated oxygen sensor (front) monitor

｠
