DTC P0132, P0152 HO2S1

PFP:22690

Component Description

ABS004DN

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 1 to 0V.

CONSULT-II Reference Value in Data Monitor Mode

ABS004DO

Specification data are reference values.

On Board Diagnosis Logic

ABS004DP

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

DTC Confirmation Procedure

ABS004DQ

NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch “OFF” and wait at
least 10 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 10 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-228, "Diagnostic Procedure"

.

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-228, "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. Therefore,
using CONSULT-II is recommended.

On Board Diagnosis Logic

ABS004DX

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

ABS004DY

CAUTION:

Always drive vehicle at a safe speed.

NOTE:
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

°

F).

●

Before performing the following procedure, confirm that battery voltage is more than 11V at idle.

WITH CONSULT-II

1.

Start engine and warm it up to normal operating temperature.

2.

Stop engine and wait at least 10 seconds.

3.

Turn ignition switch “ON” and select “HO2S1 (B1) P0133” or “HO2S1 (B2) P0153” of “HO2S1” in “DTC
WORK SUPPORT” mode with CONSULT-II.

4.

Touch “START”.

5.

Start engine and let it idle for at least 3 minutes.

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 dis-
played on the CONSULT-II screen. Maintain the conditions con-
tinuously until “TESTING” changes to “COMPLETED”. (It will
take approximately 20 to 50 seconds.)

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