DIAG 15
Fiche n° 27
EMISSION OF POLLUTANTS
XR25 aid:None
No fault bargraphs should be illuminated.NOTES
0.97 ≤ λ ≤ 1.03
at 2500 rpm.The oxygen sensor loops correctly at 2500 rpm.
If CO > 0.3 % at 2500 rpm.
NOTES 0.97 ≤ λ ≤ 1.03
at 2500 rpm.The oxygen sensor does not loop correctly at 2500 rpm.
There is a fault with the injection or the sensor.
The catalytic converter is faulty.
NOTE : it is vital to determine the cause of the catalytic converter damage to
avoid a new converter also being damaged.
If λ < 0.97 or λ > 1.03 at idle speed
Check the sensor earth and heating.
Check there is no air leak at the manifold.
