Today I bought and installed a genuine Bosch MAF on the car. Of course now the car is going better and no messing arround in the the cold. Before I received the following error:
For the intake air temperature sensor, it first shows -30 degrees, and later at some point reaches 18 degrees and holds there.
Lambda integrator shows a too high signal and stores it as an error.
Furthermore, apparently the culprit was the maf, so I installed it, overturned errors, and hoped that all the problems are over, but however,
soon reappeared the error intake air temperature sensor, as before, at cold shows -30, later 18 degrees Celsius. Also shortly after min, two driving, again the error occurs Lambda sensor integrator.
Now follow the graph parameters, what is happening at idle and at 4000 rpm.
ow the error occurs as soon as the error is reset.
The engine revs constantly varies generally between 800 and 840 rpm (because oflambd I presumea, later in graphs)
A graph showing the preferred and the amount of air supplied to the engine, linked to revolutions:
It can be seen that the sensor works nicely
Added to the previous graph voltage sensor air flow:
As far as I see it, everything is ok
Graph rpms and signal (in Volts) lambda probes:
You can clearly see that when it changes, ie jumps lambda value with approximately 80 mV to 750 mV and falls again, that is constantly varying min and max values in the same interval and vary the engine speed. My guess is that the engine is trying to "adjust" to the lambda signal.
The following graph show the engine speed, the voltage lambda sensor, lambda lambda integrator and status:
We can see again the lambda voltage increase, with the Voltage grows the engine rpm, that goes with the min max values. A status lambda goes from poor to rich mixture constantly, which is logical.
Another graph in which it can be seen:
On the next graph shows a lot of parameters that tell the story mentioned above.
The following is a graph where the engine is running at about 4000 rpm
Lambda signal again jumps from min to max, and vice versa in circle. Air flow sensor works great, as far as I understand it. I do not understand the integrator reading ...
And finally one more charts of engine speed and signals a lambda:
It even works somewhat stable, but later returned to his old ...
Lambda was changed before 2 years, placed the original Bosch ...
Thanks to everyone for the advice to solve problem.
