MONITOR DESCRIPTION
HINT:
”Learning value” used in here represents a correction learning value of the fuel addition volume to raise the
DPNR (*4) catalyst temperature to a target range.
*4: Diesel Particulate−NOx Reduction system.
In order to detect malfunction in the exhaust fuel addition injector, the ECM monitors: the air−fuel ratio, DPNR
catalytic temperature and learning value.
SWhen the exhaust fuel addition injector adds fuel during NOx reduction, the ECM monitors the air−fuel
ratio when the exhaust fuel addition injector adds fuel. If the air−fuel ratio is too RICH or too LEAN
against the ECM predetermined air−fuel ratio, the ECM judges the fuel addition volume small or large,
and illuminates the CHK ENG. In this malfunction, there is no fail−safe operation.
SThe ECM always monitors the DPNR catalytic converter temperature and the air−fuel ratio. When the
temperature reaches higher than its usual level or the air−fuel ratio becomes extremely RICH, the ECM
judges that the injector has stuck open and illuminates the CHK ENG. If this malfunction occurs, the
ECM enters the fail−safe mode to limits its acceptable vehicle speed to approximately10 km/h (6 mph)
at maximum by restraining the engine power.
SUnder DPNR catalyst regeneration, the ECM monitors the learning value. Normally, the learning value
for the DPNR catalyst regeneration is in the vicinity of1.0. Thus the learning value is at1.4 or more
for a certain period of time, the ECM judges the fuel addition volume from the injector insufficient and
illuminates the CHK ENG. If this malfunction occurs, the ECM enters the fail−safe mode to limit its ac-
ceptable vehicle speed to approximately 80 km/h (50 mph) at maximum by restraining the engine pow-
er.

*5: The DPNR catalytic converter temperature will not reach 800_C(1,472_F) or higher during idling even
if the exhaust fuel addition injector has stuck open.
*6: While the DPNR catalyst regeneration is exercised, the ECM raises the DPNR catalytic converter temper-
ature to more than approximately 600_C(1,112_F) by adding fuel using the exhaust fuel addition injector.
If the temperature does not reach that temperature regardless of the attempt, the correction learning value
of the fuel addition volume increments to raise the DPNR catalytic converter temperature to a target range.

INITIALIZATION
1. RESET MEMORY
CAUTION:
Perform the RESET MEMORY (AT initialization) when replacing the automatic transaxle assy, engine
assy or ECM.
NOTICE:
Hand−held tester only
HINT:
The ECM memorizes the condition that the ECT controls the automatic transaxle assy and engine assy ac-
cording to those characteristics. Therefore, when the automatic transaxle assy, engine assy, or ECM has
been replaced, it is necessary to reset the memory so that the ECM can memorize the new information.
Reset procedure is as follows.
(a) Turn the ignition switch off.
(b) Connect the hand−held tester to the DLC3.
(c) Turn the ignition switch to the ON position and push the hand−held tester main switch on.
(d) Select the item ”DIAGNOSIS / OBD/MOBD”.
(e) Perform the reset memory procedure from the ENGINE menu.

INSPECTION PROCEDURE
HINT:
Intelligent tester II only:
Malfunctioning areas can be found using the Active Test / A/F Control operation. The A/F Control operation
can determine if the heated oxygen sensor or other potential trouble areas are malfunctioning or not.
(a) Perform the Active Test using the intelligent tester II.
HINT:
The A/F Control operation lowers the injection volume by 12.5 % or increases the injection volume by 25
%.
(1) Connect the intelligent tester II to the DLC3.
(2) Start the engine and turn the intelligent tester II ON.
(3) Warm up the engine by running the engine at 2,500 rpm for approximately 3 minutes.
(4) On the intelligent tester II, select the following menu items: Powertrain / Engine and ECT / Active
Test / A/F Control.
(5) Select the following monitor items: O2S B1 S1 and O2S B1 S2.
(6) Perform the A/F Control operation with the engine in an idling condition (press the right or left
button).
Result:
The heated oxygen sensor reacts in accordance with increases and decreases of the injection
volume:
+25 % → Rich output: More than 0.5 V
–12.5 % → Lean output: Less than 0.4 V
NOTICE:
Sensor 1 (front sensor) has an output delay of a few seconds. Sensor 2 (rear sensor) has a maximum
output delay of approximately 20 seconds.

The following A/F Control procedure enables the technician to check and graph the voltage output of both
the heated oxygen sensors.
To display the graph, select the following menu items on the tester: View / Line Graph.
NOTICE:
If the vehicle is short of fuel, the air–fuel ratio becomes lean and the heated oxygen sensor DTCs will
be recorded, and the MIL then illuminates.
HINT:
Read freeze frame data using the intelligent tester II. Freeze frame data record the engine condition
when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the
vehicle was moving or stationary, if the engine was warmed up or not, if the air–fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
A high heated oxygen sensor (sensor 1) voltage (0.5 V or more) could be caused by a rich air–fuel
mixture. Check for conditions that would cause the engine to run rich.
A low heated oxygen sensor (sensor 1) voltage (0.4 V or less) could be caused by a lean air–fuel mix-
ture. Check for conditions that would cause the engine to run lean.
