- removing sensors like Lambda and ISCV connector without having any MIL code error, is that the case for your Cuore?

Mine doesn't exist anymore due to a rather extraordinary engine failure. For almost 2 years since, I'm on the road by a Citroen C1... so I don't have the possibility to go to my car and try out.

But, concerning the lambda sensor, I can tell you, that it normally takes a good time (some, maybe even some dozens of km to drive) until you get the MIL for its defect. I never disconnected it just to test the diagnostic system, but I used to drive the Car with various mixtures of Ethanol fuel, up to 85% ethanol, which tended to result in a lean mixture sooner or later, so the EFI would suspect a defectuous lambda sensor and activate the MIL. But, this never took place instantly. It took, depending on the fuel-ethanol-mix and on how full the Tank was, some km to happen. I don't remember exactly, but it was I'd say 20km at least until the MIL appeared.

Once, I had also a defect lambda sensor. At first, when I deleted the error code, it took months to reapear, and that time shortened more and more, until the defect became indeniable. So: The surveillance of that sensor is error-tolerant. The error must be recognized repeatedly before the MIL is activated.

- what is the EPS 57 code?

I spent last night maybe an hour or more, trying to find out. I could not. But, I don't have the official manual with the error code list.

But: Since this is not the MIL, it doesn't concern the EFI. EPS stands for "electric power steering". So, if the power Steering works correctly (if present at all!) and the light is off in normal operation mode, who cares?

Its an electric power steering. Either it works as it should or it doesn't. One doesn't need a Warning light to distinguish. I experienced myself what it feels like, when the power steering fails. This was due to a very weak, in fact dead battery (had a short circuit in one of its cells, as I found out soon after). You really need a lot of force to turn the wheel then. Much more than in the same car without power steering. Of course, the EPS light then turned on.
