1. A/F CONTROL
HINT:
Intelligent tester only:
Malfunctioning areas can be identified by performing the A/F CONTROL function provided in the
ACTIVE TEST. The A/F CONTROL function can help to determine whether the Air-Fuel Ratio (A/F)
sensor, Heated Oxygen (HO2) sensor and other potential trouble areas are malfunctioning.
The following instructions describe how to conduct the A/F CONTROL operation using an intelligent
tester.
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine and turn the tester on.
(c) Warm up the engine at an engine speed of 2500 rpm for approximately 90 seconds.
(d) On the tester, select the following menu items: DIAGNOSIS / ENHANCED OBD II / ACTIVE
TEST / A/F CONTROL.
(e) Perform the A/F CONTROL operation with the engine in an idling condition (press the RIGHT or
LEFT button to change the fuel injection volume).
(f) Monitor the voltage outputs of the A/F and HO2 sensors (AFS B1S1 and O2S B1S2 or AFS
B2S1 and O2S B2S2) displayed on the tester.
HINT:
• The A/F CONTROL operation lowers the fuel injection volume by 12.5% or increases the
injection volume by 25%.
• Each sensor reacts in accordance with increases and decreases in the fuel injection volume.
Standard voltage
CAUTION:
The Air-Fuel Ratio (A/F) sensor has an output delay of a few seconds and the Heated
Oxygen (HO2) sensor has a maximum output delay of approximately 20 seconds.

outputs of both the A/F and HO2 sensors.

press the F4 button.
INSPECTION PROCEDURE
HINT:
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle was running or stopped, whether the engine was
warmed up or not, whether the air-fuel ratio was lean or rich, as well as other data recorded at the time of
a malfunction.

CHECKING MONITOR STATUS
The purpose of the monitor result (mode 06) is to allow
access to the results for on-board diagnostic monitoring tests
of specific components/systems that are not continuously
monitored. Examples are catalyst, evaporative emission
(EVAP) and thermostat.
The monitor result allows the OBD II scan tool to display the
monitor status, test value, minimum test limit and maximum
test limit. These data are displayed after the vehicle has been
driven to run the monitor.
When the test value is not between the minimum test limit
and maximum test limit, the ECM (PCM) interprets this as a
malfunction. When the component is not malfunctioning, if the
difference of the test value and test limit is very small, the
component will malfunction in the near future.
Perform the following instructions to view the monitor status.
Although the Lexus diagnostic tester is used in the following
instructions, it can be checked using a generic OBD II scan
tool. Refer to your scan tool operator's manual for specific
procedures.
1. PERFORM MONITOR DRIVE PATTERN
The monitor results and test values can be checked with
the OBD II scan tool or the intelligent tester. The engine
control module (ECM) monitors the emissions-related
components such as the thermostat, catalyst converter
and evaporative emissions (EVAP), and determines
whether they are functioning normally or not. When
monitoring is finished, the ECM stores the monitor
results and the test values. The monitor result indicates
whether the component is functioning normally or not.
The test value is the value that was used to determine
the monitor result. If the test value is outside of the test
limit (malfunction criterion), the ECM determines the
component is malfunctioning. Some emissions-related
components have multiple test values to determine
monitor result. If one of these test values is outside of the
test limit, the ECM determines the component is
malfunctioning.
(a) Connect the intelligent tester to the DLC3.
(b) Start the engine and turn the tester on.
(c) Clear the DTCs.
(d) Run the vehicle in accordance with the applicable
drive pattern described in READINESS MONITOR
DRIVE PATTERN (See page ES-22). DO NOT turn
the ignition switch off.
NOTICE:
The test results will be lost if the ignition switch
is turned off.
