Nissan Primera P11. Instruction — part 144
On Board Diagnosis Logic
NLEC0097
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
NLEC0098
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
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 (B1)” 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 3,200 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
1,700 - 3,200 rpm
Vehicle speed
Above 64 km/h (40 MPH)
B/FUEL SCHDL
Above 3.0 msec
Selector lever
Suitable position
If “TESTING” is not displayed after 5 minutes, retry from
step 2.
6)
Make sure that “OK” is displayed after touching “SELF-DIAG

EC-QG-136.
Overall Function Check
NLEC0099
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 (HO2S1 sig-
nal) 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-QG-136.

CHECK INPUT SIGNAL CIRCUIT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 62 and heated oxygen sensor 1 (front) harness connector terminal 2.
Refer to wiring diagram.
Continuity should exist.
3. Check harness continuity between ECM terminal 62 (or terminal 2) and ground.
Continuity should not exist.
4. Also check harness for short to power.
