DTC P0132, P0152 HO2S1

PFP:22690

Component Description

UBS00DUX

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.

CONSULT-II Reference Value in Data Monitor Mode

UBS00DUY

Specification data are reference values.

On Board Diagnosis Logic

UBS00DUZ

To judge the malfunction, the diagnosis checks that the heated oxy-
gen sensor 1 output is not inordinately high.

DTC Confirmation Procedure

UBS00DV0

NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.

 WITH CONSULT-II

1.

Start engine and warm it up to normal operating temperature.

2.

Turn ignition switch OFF and wait at least 5 seconds.

3.

Turn ignition switch ON.

4.

Select “DATA MONITOR” mode with CONSULT-II.

5.

Restart engine and let it idle for 2 minutes.

6.

If 1st trip DTC is detected, go to 

EC-1380, "Diagnostic Proce-

dure"

 .

 WITH GST

1.

Start engine and warm it up to normal operating temperature.

2.

Turn ignition switch OFF and wait at least 10 seconds.

3.

Restart engine and let it idle for 2 minutes.

4.

Turn ignition switch OFF and wait at least 10 seconds.

5.

Restart engine and let it idle for 2 minutes.

6.

Select MODE 3 with GST.

7.

If DTC is detected, go to 

EC-1380, "Diagnostic Procedure"

 .

●

When using GST, DTC Confirmation Procedure should be performed twice as much as when using
CONSULT-II because GST cannot display MODE 7 (1st trip DTC) concerning this diagnosis. There-
fore, using CONSULT-II is recommended.

Specification data are reference values and are measured between each terminal and ground.

CAUTION:

Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than the ECM terminals, such as the ground.
