188.8.131.52. Conditions of storing of codes malfunctions (P0133 code)
The control unit the engine brings the P0133 code in memory and the control lamp of malfunction of a control system of the engine if in two cycles of driving of EBU parameters given are not defined below lights up.
1. During 2 mines of EBU should define factor of compensation of a fuel component of a mix more than 85 % or less than 95 %.
2. EBU should make some correction fuel - an air mix, when:
– frequency of rotation of a cranked shaft is in limits of 1600-3200 mines-1;
– loading of the engine is in limits of 1,35-3,4 ms;
– the temperature catalytic converter is higher than 372 °C;
– the system is in the closed cycle of regulation.
The conclusion of this code specifies that EBU does not correct properly structure fuel воздуш - ache mixes on signals of the forward oxygen sensor or does not correct it with demanded periodicity after warming up of the engine or at normal power setting.
