Description

INFOID:0000000001095657

The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.

DTC Logic

INFOID:0000000001095658

DTC DETECTION LOGIC

To judge the malfunction of heated oxygen sensor 1, this diagnosis
measures response time of heated oxygen sensor 1 signal. The time
is compensated by engine operating (speed and load), fuel feedback
control constant, and heated oxygen sensor 1 temperature index.
Judgment is based on whether the compensated time (heated oxy-
gen sensor 1 cycling time index) is inordinately long or not.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.

TESTING CONDITION:
Always perform at a temperature above -10

°

C (14

°

NOTE:
Never raise engine speed above 3,600 rpm after this step. If the engine speed limit is exceeded,
return to step 5.

6.

When the following conditions are met, “TESTING” will be displayed on the CONSULT-III screen. Maintain
the conditions continuously until “TESTING” changes to “COMPLETED”. (It will take approximately 40 to
50 seconds.)

CAUTION:

Always drive vehicle at a safe speed.

If “TESTING” is not displayed after 5 minutes, retry from step 2.

7.

Touch “SELF-DIAG RESULTS”.

Which displayed on COUSULT-III screen?

OK
