DTC P0134, P0154 HO2S1
Revision; 2004 April
2003 Murano
DTC P0134, P0154 HO2S1
PFP:22690
Component Description
ABS004E4
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
ABS004E5
Specification data are reference values.
On Board Diagnosis Logic
ABS004E6
Under the condition in which the heated oxygen sensor 1 signal is
not input, the ECM circuits will read a continuous approximately
0.3V. Therefore, for this diagnosis, the time that output voltage is
within 200 to 400 mV range is monitored, and the diagnosis checks
that this time is not inordinately long.

DTC Confirmation Procedure
ABS004E7
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:
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.
Select “HO2S1 (B1) P0134” or “HO2S1 (B2) P0154” of “HO2S1” in “DTC WORK SUPPORT” mode with
CONSULT-II.
3.
Touch “START”.
4.
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 4.
5.
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 10 to 60 seconds.)
If “TESTING” is not displayed after 5 minutes, retry from
step 2.
6.
Make sure that “OK” is displayed after touching “SELF-DIAG
RESULTS”. If “NG” is displayed, refer to

Overall Function Check
ABS004E8
Use this procedure to check the overall function of the heated oxygen sensor 1 circuit. During this check, a
DTC might not be confirmed.
WITH GST
1.
Start engine and warm it up to normal operating temperature.
2.
Set voltmeter probes between ECM terminal 35 [HO2S1 (B1) signal] or 16 [HO2S1 (B2) signal] and
engine ground.
3.
Check the following with engine speed held at 2,000 rpm con-
stant under no load.
The voltage does not remain in the range of 0.2 to 0.4V.
