DESCRIPTION

Tech Tips

DTC P013613 and P01361C are applicable to Euro-OBD and Brazil OBD only.

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 or Short in Heated Oxygen Sensor Circuit (DTC P013617 or P01361C)

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 will be an extremely 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.

When the target air fuel ratio is lean and the output voltage is higher than 0.71 V (rich) during active air fuel ratio control, the ECM determines that the sensor output voltage is abnormally high and stores DTC P01361C.

Tech Tips

*: 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.

Malfunctioning areas can be identified by performing the Active Test "Control the Injection Volume for A/F Sensor". This Active Test can help to determine whether the air fuel ratio sensor, heated oxygen sensor and other potential trouble areas are malfunctioning.

The following procedure describes how to perform the Active Test "Control the Injection Volume for A/F Sensor" using the GTS.

Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.

O2 Sensor Voltage B1S2 (Heated oxygen)	12.5%	Rich	Higher than 0.55 V
O2 Sensor Voltage B1S2 (Heated oxygen)	-12.5%	Lean	Below 0.4 V

Note

The air fuel ratio sensor has an output delay of a few seconds and the heated oxygen sensor has a maximum output delay of approximately 20 seconds.

Performing the Active Test "Control the Injection Volume for A/F Sensor" allows the output voltage of the air fuel ratio sensor and heated oxygen sensor to be checked and graphed.
To display the graph, enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Injection Volume for A/F Sensor / Data List / A/F (O2) Sensor Voltage B1S1 and O2 Sensor Voltage B1S2; and then press the graph button on the Data List view.

PERFORM ACTIVE TEST USING GTS (CONTROL THE EGR STEP POSITION)

Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Put the engine in Inspection Mode (Maintenance Mode).

Powertrain > Hybrid Control > Utility

Tester Display

Inspection Mode
Start the engine and warm it up until the engine coolant temperature is 75°C (167°F) or higher.

Tech Tips

The A/C switch and all accessories should be off.

Enter the following menus: Powertrain / Engine / Active Test / Control the EGR Step Position / Data List / Intake Manifold Absolute Pressure, EGR Step Position and Engine Independent.

Powertrain > Engine > Active Test

Active Test Display
Control the EGR Step Position

Data List Display
Intake Manifold Absolute Pressure
EGR Step Position
Engine Independent

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.

Note

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".

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

Tech Tips

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.

Result	Proceed to
The value of Intake Manifold Absolute Pressure increases by 10 kPa(abs) or more, compared to when the EGR valve was fully closed (0 step)	OK
Other than above	NG

Tech Tips

10 kPa = 1.45 psi

CLEAR DTC

Connect the GTS to the DLC3.
Turn the power switch on (IG).
Turn the GTS on.
Clear the DTCs.

CHECK WHETHER DTC OUTPUT RECURS

Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.

Powertrain > Engine > Utility

Tester Display

All Readiness
Input the DTC: P013613, P013617 or P01361C.

Check that the DTC judgment result is NORMAL. If the DTC judgment result is INCOMPLETE, perform the confirmation drive pattern again but increase the vehicle speed.

Result

Proceed to

NORMAL

(DTCs are not output)

ABNORMAL

(DTC P013613, P013617 or P01361C is output)
