2.5.3.7. Sensor of provision of a butterfly valve

Butterfly valve jamming in closed (below expected) / opened (above expected) situation (P0121)
If the PCM block finds out that the corner of opening of a butterfly valve – less than 12,5 % during 5 with the ambassador of approach of the following conditions, the PCM block decides that the butterfly valve is blocked in a closed position:
– the temperature of cooling liquid of the engine – is higher than 80 °C;
– a signal of the sensor of pressure in an inlet collector – more than 32,0 g / with;
– if the PCM block finds out that the corner of opening of a butterfly valve – more than 50 % during 5 with the ambassador of approach of the following conditions, the PCM block decides that the butterfly valve is blocked in open situation:
– frequency of rotation of the engine – is higher than 500 mines-1;
– a signal of the sensor of pressure in an inlet collector – 0 g/pages.

Low level of an entrance signal of a chain of provision of a butterfly valve (P0122)
If the PCM block finds tension of the sensor of provision of a butterfly valve in a conclusion of 2 A of the PCM block – below 0,1 In the ambassador of inclusion of ignition, the PCM block decides that the chain of provision of a butterfly valve has malfunction.

High level of an entrance signal of a chain of provision of a butterfly valve (P0123)
If the PCM block finds tension of the sensor of provision of a butterfly valve in a conclusion 2 And the PCM block – above 4,9 In the ambassador of inclusion of ignition, the PCM block decides that the chain of provision of a butterfly valve has malfunction.

There is no response of the forward sensor of concentration of oxygen with heating at enrichment of a mix (P0131)
The PCM block supervises entrance tension of the forward sensor of concentration of oxygen with heating when the following conditions are satisfied.
– frequency of rotation of the engine – is higher than 1500 mines-1;
– the temperature of cooling liquid of the engine – is higher than 80 °C.
If entrance tension of the sensor is lower 0,45 In during 41,2 with, the PCM block decides that the forward sensor of concentration of oxygen is not switched.

There is no response of the forward sensor of concentration of oxygen with heating at pauperization of a mix (P0132)
The PCM block supervises entrance tension of the forward sensor of concentration of oxygen with heating when the following conditions are satisfied.
– frequency of rotation of the engine – is higher than 1500 mines-1;
– the temperature of cooling liquid of the engine – is higher than 80 °C.
If entrance tension of the sensor is higher 0,45 In during 41,2 with, the PCM block decides that the forward sensor of concentration of oxygen is not switched.

Malfunction of a chain of the forward sensor of concentration of oxygen with heating (P0133)
The PCM block supervises the period of a cycle of inversion, switching time "poor-rich" and "rich-poor". The PCM block calculates the average period of a cycle of inversion, average time of switching "poor-rich" and "rich-poor" when the following conditions are satisfied:
– movement 3 mode;
– settlement loading of 14,8-59,4 % (at 2000 mines-1.);
– frequency of rotation of the engine 1410-4000 of mines-1 (model with a mechanical transmission);
– frequency of rotation of the engine 1190-4000 of mines-1 (model with an automatic transmission);
– speed of a vehicle – is higher than 3,76 km/h;
– the temperature of cooling liquid of the engine is higher than 10 °C;
– a cycle of inversion of a signal of the forward sensor of concentration of oxygen with heating – more than 10 cycles.
If any of settlement sizes exceeds threshold value, the PCM block decides that the chain has malfunction.

There is no signal of a chain of the forward sensor of concentration of oxygen with heating (P0134)
The PCM block supervises entrance tension of the forward sensor of concentration of oxygen with heating when the following conditions are satisfied:
– frequency of rotation of the engine – is higher than 1500 mines-1.
– the temperature of cooling liquid of the engine – is higher than 80 °C.
If entrance tension of the sensor never exceeds 0,55 In during 83,2 with, the PCM block decides that the chain of the sensor does not become more active.

High level of an entrance signal of a chain of the back sensor of concentration of oxygen with heating (P0138)
The PCM block supervises entrance tension of the back sensor of concentration of oxygen with heating. If entrance tension of the back sensor of concentration of oxygen with heating – above 0,45 In during 6,4 with the ambassador of interruption of supply of fuel, the PCM block decides that level of an entrance signal is overestimated.

There is no signal of a chain of the back sensor of concentration of oxygen with heating (P0140)
The PCM block supervises target tension of the back sensor of concentration of oxygen with heating when the following conditions are satisfied:
– frequency of rotation of the engine – is higher than 1500 mines-1.
– the temperature of cooling liquid of the engine – is higher than 80 °C
If entrance tension from the sensor does not exceed 0,55 In during 30,4 with, the PCM block decides that the chain of the sensor does not become more active
