Opel Corsa D 1.2 ecotec likely fuel issue

[Danyit84]

So guys I have a Opel Corsa D 1.2 petrol engine with egr bypassed mechanically, but not electronically, and the air filter to the panel. Around 2000 rpm wire of the gas, the car strattona, and I get error in the diagnosis of the mixture is lean.
I thought it was due to the oxygen sensor immediately after the filter, and I cleaned the svitol but nada, the problem ? remained. I soaked it in thinner, and has worked for a couple of days, then again the same problem, in demolition I recovered a sensor of another Opel, Tigra precisely, they have different codes, and in fact after a few metres the problem ? re-presented.
I noticed that by removing the plug from said sensor, the drive reads minus 40 degrees. I thought if it reads a low temperature, inietter? automatically ir? of gas, then I put it in the bike and did a test, are the 5-6 days that the car walking with the cable unplugged and it goes perfectly.
Which pu? be the problem? I wanted to check the lambda sensor, but it uses 2, I come from a car, a p? pi? old I do not know what can serve the second, and which of the two I should go check it out, I probably should proceed to trial.

PS having their hands an instrument diy air/fuel tuning very and very reliable, I decided to do a test, I connected it to the first lambda and light the first led of the good, so usually I ? seemed to be a confirmation of that detected in the control unit. Then release the gas all the leds light up, even those of the fuel mixture rich... but I think that is normal...

Thanks to all, and aiutatemiiiiiii

meanwhile, a council chr you do and to never clean the lambda probes with thinner svitol or other substances, as the probes are very sensitive,then for qusnto is related to the problem, the causes may be many, the lambda probe is blocked,the temperature sensor, try to check the throttle body if and dirt and eventually to make a cleaning of the throttle body, then if you have a diagnosis test to see if there are any errors or to check the values you give us more info.

Joseph thanks a lot for the info... the throttle body ? clean, I have the vapours of the oil in the canister, I thought of a problem with the lambda sensor, but I have 2... so I don't know how to move, given that I do not know the operation of the dual probe...
The diagnosis to me, with the oxygen sensor stuck after a p? of use, error mixture is lean, the other errors there are... real-time parameters may be useful for you to see?

PS with oxygen sensor disconnected no error and the car is fine...

The first lambda probe (the one closest to the drain) must give a sinusoidal signal take a tester or would it be better with an oscilloscope if you opt for the tester set this to 5 volts locates the wire color black speli a little, take the red lead and put it in the black wire and the tip of the tester black connect to ground and see if the value ranges from o to 5 volts if it does not work set the tester up to 1 volt, now I don't remember those probes that value should be, however, it does not matter the most important thing is that the probe brush up and down?.
The second probe has to give a fixed value.
I state one thing that if there are in-leakage of air or if a candela is not burning this can distort the data of the probe making it the block or to a positive value or a negative value then first of all check if there is leakage, or if the engine turns bad because spark plugs or injectors.

Thanks giuseppeturbo... very kind... Just the avr? a moment to? these tests and you will upgrade?... as you well know, you always make the machines of the other, but for their you don't ever have time :-D

[alfonsoh]

you only have problems mixture is lean?

According to me, the car does not make anything!

[Danyit84]

Alfonsoh, what do you mean??? I did not understand...

[alfonsoh]

by removing the egr on that car does not make nothing, you've tried to rely on a filter open to increase the pressure in the intake, the problem with that cos? making you have a pressure next to the reflux of the egr, but the air-and oxygen-rich in comparison to the exhaust gas, and then the fuel mixture to force risulter? lean.
The you need to bulk up from the map and not the least.... the lambda, according to me, it has nothing to do.
? a change that you are using to much or you just made?

I confirm what it says alfonsoh, try to remove the mechanical closure of the egr,and as a diesel in the benza it greatly reduces the carburetor,pull the battery for about ten minutes,hang up and try... you'll see that everything is normal,but if not, check the probe....

[Danyit84]

Zac, the egr ? bypassed mechanically, but ? electronically active...
alfonsoh, but in fact, I wrote that an instrument connected to the probe, confirms to me that the fuel mixture ? lean... appropriately for the changes...? for the sake I wanted to check the probes...
I know that you can? grease the fuel mixture even without the need to intervene in the map, I have to look for a p? around to find it... you do? know...
The Race is mounted on a control unit of the hybrid and some stubborn to rimapparla have stuck, some times even after 2-3 days of normal use of the car... then I would like to avoid rimapparla...
Thanks for the advice...
