Renault Megane I 1.6 16V II Lambda Probe: Immobilizer Ring, Knock Sensor, and Voltage Issues

Hello all.
Currently, I am dealing with Renia, sister-in-law, as in the title. After connecting the car to the computer (Delphi) three errors came up:
- a problem with the immobilizer ring (it was fired on another key, I'm not worried about it for now)
- the knock sensor is also not a permanent error - it can be deleted
-the lambda sensor behind the catalytic converter, i.e. the lower one, here on idle as well as on the gas flow, the value is kept at about 450 mV and there is an error of this probe, but also not as a permanent one.
Today, when measuring with an ordinary meter I noticed that on the upper probe (in front of the catalyst) there is 12v voltage to heat the probe, while on the second probe is only +. Is that supposed to be if I have a bunch of beams somewhere or do not let my computer run.
I am counting on your help and history

Hey.
How exactly is the error in Delphi described?
As for the beam, I would not turn my head away. First you have to start with the probe. Start by checking the cable (the one that is with the probe) is not damaged.
But first, enter the name of this probe error.

The error is:
DF 058 - Sonada lambda behind the catalytic converter
- discontinuous
DF-058 -Tile oxygen sensor
- discontinuous

I have tested the beams from the first and second probes and all the cables have continuity. So hope that the cable that was released fell out. ECU after visual inspection as new but realizes that it is not a determinant.
The probe on the heater is about 10?

welcome back
At the beginning of the first post I wrote that I have an immobilizer error and that I do not worry about it, but I slowly change my mind. I get two errors as permanent but to be removed and after 4-5 km on a warm engine did not appear.
- 054 Power supply to the reader, short-circuit to + 12v power supply. Permanent
- 054 Power supply to the reader ring, open circuit or short to ground. Permanent
Central all kinds of interior lighting, etc. works normally, the engine has power does not go out, the indicator lamp on the dashboard (red) blinks after removing the key with a frequency of about once every 2-3 seconds when the engine ignited once. There is also the error of the second probe as discontinuous
DF058 - Lambda probe after catalytic converter, Not continuous but after 4-5 km appeared again. The probe replaced with a new DENSO. Fuses of the battery wheel - right side on the shaft without traces of rust, etc. I am worried about lack of mass on the candle heating (on the first everything ok), cables checked between EKU and probes and all have a transition with one that had resistance about 3 times greater than the other wires - unfortunately I do not think which one

Hey
I see that the problem arises after the problem. Unfortunately, it got me too ...
Have you tried to disconnect the reader and then check the errors? If after disconnection the same error pops up, it may mean that something in the beam is not there. All fuses checked out?
Did you buy the probe under this mode? Is it universal?

A universal probe but with a vin number and a guest who has extensive experience in the trade of automotive parts. Fuses ok. In this car is a key not a card because I think that's what you mean with the reader?

Hello all.
Some time has passed since the completion of the repair of this car. The error of heating the second lambda lambda sensor is a sporadic error, the probe practically shows 0 MV so I take it as a good coin. The check has not been lit for about half a year and there is no other error.
