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 Threshold and the air fuel ratio sensor (sensor 2) current is -0.25757 mA or more.

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.
HINT:
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:
The air fuel ratio sensor (sensor 1) has an output delay for a few seconds and the air fuel ratio sensor (sensor 2) has a maximum output delay of approximately 20 seconds.
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.
