MONITOR DESCRIPTION

Active Air fuel Ratio Control


The ECM usually performs air fuel ratio feedback control so that the air fuel ratio sensors 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 air fuel ratio sensor (sensor 2) (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 Air Fuel Ratio Sensor (Sensor 2) Output Current (DTC P013616)


Case 1: The ECM illuminates the MIL and stores a DTC when active rich air-fuel ratio control is being performed and the air fuel ratio sensor (sensor 2) current is 6 mA or more.

Case 2: The ECM illuminates the MIL and stores a DTC when active rich air-fuel ratio control is being performed, the oxygen storage capacity of the catalyst is more than 2.0 g and the air fuel ratio sensor (sensor 2) current is -0.25757 mA or more.

Abnormal Air Fuel Ratio Sensor (Sensor 2) Output Current During Fuel-cut from Rich Condition (DTC P013A7C)


During a fuel cut, if the amount of time it takes for the current of the air fuel ratio sensor (sensor 2) to increase to a certain amount is equal to or greater than the threshold, the responsiveness of the air fuel ratio sensor (sensor 2) is judged as degraded, the ECM illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN

HINT:
·

This confirmation driving pattern is used for the "Perform Confirmation Driving Pattern" procedure of the following diagnostic troubleshooting procedure.

·

Performing this confirmation driving pattern will activate the air fuel ratio sensor (sensor 2) monitor (the catalyst monitor is performed simultaneously). This is very useful for verifying the completion of a repair.

·

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

CAUTION / NOTICE / HINT

HINT:

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 sensors (sensor 1 and sensor 2) 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.


1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON.

3.

Turn the GTS on.

4.

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

5.

Warm up the air fuel ratio sensors at an engine speed of 2500 rpm for 90 seconds.

6.

Enter the following menus: Powertrain / Engine / Active Test / Control the Injection Volume for A/F Sensor / Data List / A/F (O2) Sensor Current B1S1 and A/F (O2) Sensor Current B1S2.

7.

Perform the Active Test with the engine idling (change the fuel injection volume).

8.

Monitor the output current of the air fuel ratio sensor (sensor 1) (A/F (O2) Sensor Current B1S1) and air fuel ratio sensor (sensor 2) (A/F (O2) Sensor Current B1S2) displayed on the GTS.


HINT:
·

The Active Test "Control the Injection Volume for A/F Sensor" can be used to lower the fuel injection volume by 12.5% or increase the injection volume by 12.5%.

·

Each sensor reacts in accordance with the increase and decrease in the fuel injection volume.



Standard
GTS Display (Sensor) Injection Volume Status Current
A/F (O2) Sensor Current B1S1
(Air fuel ratio sensor (sensor 1)) 		12.5% Rich Below -0.075 mA
-12.5% Lean More than 0.037 mA
A/F (O2) Sensor Current B1S2
(Air fuel ratio sensor (sensor 2)) 		12.5% Rich Below -0.86 mA
-12.5% Lean More than 0.33 mA

NOTICE:

Performing the Active Test "Control the Injection Volume for A/F Sensor" allows the output value of the air fuel ratio sensors (sensor 1 and sensor 2) to be checked and graphed.

NOTICE:

Inspect the fuses for circuits related to this system before performing the following procedure.


HINT:
·

Sensor 1 refers to the sensor closest to the engine assembly.

·

Sensor 2 refers to the sensor farthest away from the engine assembly.

·

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. 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.
