Nissan Primera P11. Manual — part 154
Overall Function Check
NLEC0595
Use this procedure to check the overall function of the rear heated
oxygen sensor circuit. During this check, a 1st trip DTC might not
be confirmed.
Without CONSULT-II
1)
Start engine and drive vehicle at a speed of more than 70 km/h
(43 MPH) for 2 consecutive minutes.
2)
Stop vehicle with engine running.
3)
Set voltmeter probes between ECM terminals 63 (HO2S2 sig-
nal) and engine ground.
4)
Check the voltage when revving engine up to 4,000 rpm under
no load at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
The voltage should be below 0.56V at least once during
this procedure.
If the voltage can be confirmed in step 4, step 5 is not
necessary.
5)
Keep vehicle at idling for 10 minutes, then check the voltage.
Or check the voltage when coasting from 80 km/h (50 MPH)
in 3rd gear position.
The voltage should be below 0.56V at least once during
this procedure.
6)
If NG, go to “Diagnostic Procedure”, EC-QG-175.
