Description
INFOID:0000000004362081
The air fuel ratio (A/F) sensor 1 is a planar one-cell limit current sen-
sor. The sensor element of the A/F sensor 1 is composed an elec-
trode layer, which transports ions. It has a heater in the element.
The sensor is capable of precise measurement = 1, but also in the
lean and rich range. Together with its control electronics, the sensor
outputs a clear, continuous signal throughout a wide range.
The exhaust gas components diffuse via the diffusion layer at the
sensor cell. An electrode layer is applied voltage, and this current
relative oxygen density in lean. Also this current relative hydrocar-
bon density in rich.
Therefore, the A/F sensor 1 is able to indicate air fuel ratio by this
electrode layer of current. In addition, a heater is integrated in the
sensor to ensure the required operating temperature of approxi-
mately 800
°C (1,472°F).
DTC Logic
INFOID:0000000004362082
DTC DETECTION LOGIC
To judge malfunctions, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 sig-
nal fluctuates according to fuel feedback control.
DTC CONFIRMATION PROCEDURE
1.
PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-
ing the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.

SEN1” in “DTC WORK SUPPORT” mode with CONSULT-III.
2. Touch “START”.
3. When the following conditions are met, “TESTING” will be displayed on the CONSULT-III screen.
If “TESTING” is not displayed after 20 seconds, retry from step 2.
CAUTION:
Always drive vehicle at a safe speed.
Is “TESTING” displayed on CONSULT-III screen?
YES
>> GO TO 5.
NO
>> Check A/F sensor 1 function again. GO TO 3.
5.
PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-II
Release accelerator pedal fully.
NOTE:
Never apply brake when releasing the accelerator pedal.
Which does “TESTING” change to?
COMPLETED>>GO TO 6.
OUT OF CONDITION>>Retry DTC CONFIRMATION PROCEDURE. GO TO 4.
6.
PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-III
Touch “SELF-DIAG RESULT”.
Which is displayed on CONSULT-III screen?
OK
>> INSPECTION END

>> Go to
EC-1227, "Diagnosis Procedure"
7.
PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION B
Perform component function check. Refer to
EC-1227, "Component Function Check"
.
NOTE:
Use component function check to check the overall function of the A/F sensor 1 circuit. During this check, a
1st trip DTC might not be confirmed.
Is the inspection result normal?
