DESCRIPTION In order to
obtain a high purification rate of the carbon monoxide (CO), hydrocarbon
(HC) and nitrogen oxide (NOx) components in the exhaust gas, a TWC
(Three-Way Catalytic Converter) is used. For the most efficient use of
the TWC, the air fuel ratio must be precisely controlled so that it is
always close to the stoichiometric air fuel level. For the purpose of
helping the ECM to deliver accurate air fuel ratio control, a heated
oxygen sensor is used. The heated oxygen sensor
is located behind the TWC, and detects the oxygen concentration in the
exhaust gas. Since the sensor is integrated with the heater that heats
the sensing portion, it is possible to detect the oxygen concentration
even when the intake air volume is low (the exhaust gas temperature is
low). When the air fuel ratio becomes lean, the
oxygen concentration in the exhaust gas is high. The heated oxygen
sensor informs the ECM that the post-TWC air fuel ratio is lean (low
voltage, i.e. less than 0.45 V). Conversely,
when the air fuel ratio is richer than the stoichiometric air fuel
level, the oxygen concentration in the exhaust gas is low. The heated
oxygen sensor informs the ECM that the post-TWC air fuel ratio is rich
(high voltage, i.e. higher than 0.45 V). The heated oxygen sensor has
the property of changing its output voltage drastically when the air
fuel ratio is close to the stoichiometric level. The
ECM uses the supplementary information from the heated oxygen sensor to
determine whether the air fuel ratio after the TWC is rich or lean, and
adjusts the fuel injection duration accordingly. Thus, if the heated
oxygen sensor is working improperly due to internal malfunctions, the
ECM is unable to compensate for deviations in the primary air fuel ratio
control.

DTC stored | SAE Code: P0159 | MONITOR DESCRIPTION
Active Air fuel Ratio Control The
ECM usually performs air fuel ratio feedback control so that the air
fuel ratio sensor output indicates a near stoichiometric air fuel level.
This vehicle includes active air fuel ratio control in addition to
regular air fuel ratio control. The ECM performs active air fuel ratio
control to detect any deterioration in the Three-Way Catalytic Converter
(TWC) and heated oxygen sensor malfunctions (refer to the diagram
below). Active air fuel ratio control is performed
for approximately 30 seconds while driving with a warm engine. During
active air fuel ratio control, the air fuel ratio is forcibly regulated
to become lean or rich by the ECM. If the ECM detects a malfunction, a
DTC is stored. Abnormal Voltage Output of Heated Oxygen Sensor (DTCs P013613 and P015613)
While
the ECM is performing active air fuel ratio control, the air fuel ratio
is forcibly regulated to become rich or lean. If the sensor is not
functioning properly, the voltage output variation is small. For
example, when the heated oxygen sensor voltage does not increase to 0.71
V or higher during active air fuel ratio control, the ECM determines
that the sensor voltage output is abnormal and stores DTC P013613 or
P015613. Open in Heated Oxygen Sensor Circuit (DTCs P013617 and P015617)
During
active air fuel ratio control, the ECM calculates the Oxygen Storage
Capacity (OSC)* of the Three-Way Catalytic Converter (TWC) by forcibly
regulating the air fuel ratio to become rich or lean. If
the heated oxygen sensor has an open circuit, or the voltage output of
the sensor noticeably decreases, the OSC indicates an extraordinarily
high value. Even if the ECM attempts to continue regulating the air fuel
ratio to become rich or lean, the heated oxygen sensor output does not
change. While performing active air fuel ratio
control, when the target air fuel ratio is rich and the heated oxygen
sensor voltage output is less than 0.21 V (lean), the ECM interprets
this as an abnormally low sensor output voltage and stores DTC P013617
or P015617. HINT: *: The TWC
has the capability to store oxygen. The OSC and the emission
purification capacity of the TWC are mutually related. The ECM
determines whether the catalyst has deteriorated based on the calculated
OSC value. Click here
High or Low Impedance of Heated Oxygen Sensor (DTCs P013611 and P015611 or P013614 and P015614)
During
normal air fuel ratio feedback control, there are small variations in
the exhaust gas oxygen concentration. In order to continuously monitor
the slight variation of the heated oxygen sensor signal while the engine
is running, the impedance* of the sensor is measured by the ECM. The
ECM determines that there is a malfunction in the sensor when the
measured impedance deviates from the standard range.
*: The effective resistance in an alternating current electrical circuit.
HINT:
- The impedance cannot be measured using an ohmmeter.
- DTC P013611 or P015611 indicates the deterioration of the heated oxygen
sensor. The ECM stores the DTC by calculating the impedance of the
sensor when the typical enabling conditions are satisfied (2 driving
cycles).
- DTC P013614 or P015614 indicates an open or short circuit in the heated
oxygen sensor (2 driving cycles). The ECM stores the DTC when the
impedance of the sensor exceeds the threshold 15 kΩ.
Extremely High Output Voltage of Heated Oxygen Sensor (DTCs P013615 and P015615)
The ECM continuously monitors the heated oxygen sensor output voltage while the engine is running.
DTC P013615 or P015615 is stored if the heated oxygen sensor voltage output is 1.2 V or higher for 10 seconds or more.
Abnormal Voltage Output of Heated Oxygen Sensor During Fuel-cut (DTCs P013623 and P015623)
The
sensor output voltage drops to less than 0.2 V (extremely lean status)
immediately when the vehicle decelerates and fuel cut is operating. If
the voltage does not drop to less than 0.2 V for 7 seconds or more, the
ECM determines that the sensor response has deteriorated, illuminates
the MIL and stores a DTC. Abnormal Voltage Output of Heated Oxygen Sensor During Fuel-cut from Rich Condition (DTCs P013A00 and P013C00)
If
the sensor output voltage does not drop from 0.35 to 0.2 V immediately
when the vehicle decelerates and fuel cut is operating, the ECM
illuminates the MIL and stores a DTC. MONITOR STRATEGY

CAUTION / NOTICE / HINT
HINT: Malfunctioning
areas can be identified by performing the Control the Injection Volume
for A/F Sensor function provided in the Active Test. The Control the
Injection Volume for A/F Sensor function can help to determine whether
the air fuel ratio sensor, heated oxygen sensor and other potential
trouble areas are malfunctioning. The following
instructions describe how to conduct the Control the Injection Volume
for A/F Sensor operation using the Techstream.
- Connect the Techstream to the DLC3.
- Start the engine.
- Turn the Techstream on.
- Warm up the engine and run the engine at an engine speed of 2500 rpm for approximately 90 seconds.
- Enter the following menus: Powertrain / Engine / Active Test / Control
the Injection Volume for A/F Sensor / Data List / A/F (O2) Sensor
Voltage B1S1 and O2 Sensor Voltage B1S2 or A/F (O2) Sensor Voltage B2S1
and O2 Sensor Voltage B2S2.
- Perform the Active Test with the engine idling (change the fuel injection volume).
- Monitor the output voltages of the air fuel ratio and heated oxygen
sensors (A/F (O2) Sensor Voltage B1S1 and O2 Sensor Voltage B1S2 or A/F
(O2) Sensor Voltage B2S1 and O2 Sensor Voltage B2S2) displayed on the
Techstream.
HINT:
- The Control the Injection Volume for A/F Sensor operation lowers the
fuel injection volume by 12.5% or increases the injection volume by
12.5%.
- Each sensor reacts in accordance with increases and decreases in the fuel injection volume.
