4.

Hold engine speed at 2,000 rpm under no load during the following steps.

5.

Touch “RECORD” on CONSULT-II screen.

6.

Check the following.

-

“HO2S1 MNTR (B1)” in “DATA MONITOR” mode changes from
“RICH” to “LEAN” to “RICH” more than 5 times in 10 seconds.

5 times (cycles) are counted as shown in the figure.

-

“HO2S1 (B1)” voltage goes above 0.6V at least once.

-

“HO2S1 (B1)” voltage goes below 0.3V at least once.

-

“HO2S1 (B1)” voltage never exceeds 1.0V.

P0133 HO2S1

Description

INFOID:0000000001089339

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:0000000001089340

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.
