2.5.3.12. Neutralization system

System effectiveness of neutralization is lower than threshold level (P0420)
The PCM block compares number of inversions of forward and back sensors of concentration of oxygen to heating during certain time. The PCM block supervises number of inversions of the back sensor at set number of inversions of the forward sensor when the following conditions are satisfied. The PCM block finds a ratio of inversions:
– frequency of rotation of the engine – 1410–3000 mines-1 (models with a mechanical transmission);
– frequency of rotation of the engine – 1281–3000 mines-1 (models with an automatic transmission);
– settlement loading of 15-50 % *.
If the ratio of inversions – below threshold level, the PCM block decides that work of system of neutralization worsened.

* the Maximum settlement value of loading changes depending on frequency of rotation of the engine
