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 ratio. 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 ratio, 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 air fuel ratio.
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 an internal malfunction, the ECM is unable to compensate for deviations in the primary air fuel ratio control.

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 ratio. 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 any malfunctions of the heated oxygen sensor (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 Heated Oxygen Sensor Output Voltage (DTC P013613)
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 variation in output voltage 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 output voltage is abnormal and stores DTC P013613.
Open in Heated Oxygen Sensor Circuit (DTC P013617)
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 output voltage 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 will not change.
While performing active air fuel ratio control, when the target air fuel ratio is rich and the heated oxygen sensor output voltage is less than 0.21 V (lean), the ECM interprets this as an abnormally low sensor output voltage and stores DTC P013617.
- 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.
High or Low Impedance of Heated Oxygen Sensor (DTCs P013611 or P013614)
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 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 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 Heated Oxygen Sensor Output Voltage (DTC P013615)
The ECM continuously monitors the heated oxygen sensor output voltage while the engine is running.
DTC P013615 is stored if the heated oxygen sensor voltage output is 1.2 V or higher for 10 seconds or more.
Abnormal Heated Oxygen Sensor Output Voltage During Fuel-cut (DTC P013623)
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 6 seconds or more, the ECM determines that the sensor response has deteriorated, illuminates the MIL and stores a DTC.
Abnormal Heated Oxygen Sensor Output Voltage During Fuel-cut from Rich Condition (DTC P013A00)
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.

Confirm that the value of Data List item Engine Independent is "Operate" then check the value of Intake Manifold Absolute Pressure while performing the Active Test.
- NOTICE:
- ·
Do not leave the EGR valve open for 10 seconds or more during the Active Test.
·Be sure to return the EGR valve to step 0 when the Active Test is completed.
·Do not open the EGR valve 30 steps or more during the Active Test.
- OK:
The value of Intake Manifold Absolute Pressure changes in response to the EGR step position when the value of Engine Independent is "Operate".
- Standard:
- Control the EGR Step Position (Active Test) 0 Steps 0 to 30 Steps Intake Manifold Absolute Pressure
(Data List)(EGR valve is fully closed) Intake Manifold Absolute Pressure value is at least +10 kPa (1.45 psi) higher than when EGR valve is fully closed
- HINT:
- ·
If the value of Data List item Engine Independent is "Not Opr" when the engine is idling, charge control is being performed. Perform the Active Test after charge control is complete ("Operate" is displayed).
·While performing the Active Test, if the increase in the value of Intake Manifold Absolute Pressure is small, the EGR valve assembly may be malfunctioning.
·Even if the EGR valve assembly is malfunctioning, rough idling or an increase in the value of Intake Manifold Absolute Pressure may occur while performing the Active Test. However, the amount that the value of Intake Manifold Absolute Pressure increases will be smaller than normal.
