Nissan Primera P11. Manual — part 236
6)
If it is impossible to adjust throttle position sensor idle position
in “Basic Inspection”, replace throttle position sensor.
Without CONSULT-II
1)
Start engine and warm it up to normal operating temperature.
2)
Stop engine (ignition switch OFF).
3)
Turn ignition switch ON.
4)
Check voltage between ECM terminal 92 (Throttle position
sensor signal) and ground under the following conditions.
NOTE:
Voltage measurement must be made with throttle position
sensor installed in vehicle.

If NG, adjust throttle position sensor idle position. Refer to
“Basic Inspection”, EC-SR-84.
5)
If it is impossible to adjust throttle position sensor idle position
in “Basic Inspection”, replace throttle position sensor.

Component Inspection (Cont’d)
EC-143
Component Description
NCEC0094
The heated oxygen sensor 1 (front) is placed into the exhaust
manifold. It detects the amount of oxygen in the exhaust gas com-
pared to the outside air. The heated oxygen sensor 1 (front) 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 (front) 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.

Component Description

On Board Diagnosis Logic
NCEC0097
Under the condition in which the heated oxygen sensor 1 (front)
signal is not input, the ECM circuits will read a continuous approxi-
mately 0.3V. Therefore, for this diagnosis, the time that output
voltage is within 200 to 400 mV range is monitored, and the diag-
nosis checks that this time is not inordinately long.
DTC No.

DTC Confirmation Procedure
NCEC0098
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 9 seconds
before conducting the next test.
TESTING CONDITION:
I
Always perform at a temperature above −10°C (14°F).
I
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) P0130” of “HO2S1” in “DTC WORK SUP-
PORT” mode with CONSULT-II.
3)
Touch “START”.
4)
Let it idle for at least 3.5 minutes.
NOTE:
Never raise engine speed above 3,200 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
continuously until “TESTING” changes to “COMPLETED”. (It
will take approximately 10 to 60 seconds.)
ENG SPEED
1,500 - 3,200 rpm
Vehicle speed
64 - 130 km/h (40 - 81 MPH)
B/FUEL SCHDL
2.4 - 11.0 msec

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

RESULTS”.
If

Procedure”, EC-SR-148.
Overall Function Check
NCEC0099
Use this procedure to check the overall function of the heated oxy-
gen sensor 1 (front) circuit. During this check, a 1st trip DTC might
not be confirmed.
Without CONSULT-II
1)
Start engine and warm it up to normal operating temperature.
2)
Set voltmeter probes between ECM terminal 62 (Heated oxy-
gen sensor 1 (front) signal) and engine ground.
3)
Check the following with engine speed held at 2,000 rpm con-
stant under no load.
I
The voltage does not remain in the range of 0.2 - 0.4V.
4)
If NG, go to “Diagnostic Procedure”, EC-SR-148.
