The right-side temperature sender is called G151 in the wiring diagram. The error message is telling you that the Air-conditioner module (J255) is unhappy with this sensor.
So this fault probably means that either the device itself, or the wiring/connector on the sensor needs renewal (I'm guessing of course).
If this was my car, I would start by investigating ALL the possible causes that I suggest with a multi-meter (the circuit is very simple - the sender has 2 x pins, one pin connects to J255 and the other pin is earthed)
This is how to access G151:
Note: my picture shows the left-side temperature sender - the right-side sender is in the same position behind the end-cover on the other side of the dash
The instructions for removing G151 are:
- Turn vent temperature sender -1- in -direction of arrow- and pull it out of mounting.
- Disconnect electrical connector -2-.
- Renew seal -3- if damaged or defective.

I replaced the sensor but it still shows the same problem. I also looked at the fuses, but they are all fine.

hmm......... OK, no thanks needed - but it does express a form of appreciation when a forum colleague helps and it's also polite forum etiquette (even if the thanks is disingenuous) - at least it's polite in my part of this lonely blue planet!! Let me try again: please re-read my previous reply (copy below) because I answered this question in my last post

So, instead of proceeding as I suggested - it appears that you decided to throw money at this problem by "replaced the sensor but it still shows the same problem".
I have never understood folk who assume that proper diagnostic practices (meaning proper-testing before spending money) can be substituted with premature guesses.
Of course it's entirely your right to proceed as you want - but I'm not sure what part of my previous reply was confusing!

PS: Please don't express thanks in a new post - to do so would be gratuitous and insincere

Hello I had already ordered the sensor through a colleague, so with a discount it didn't cost much. anyway, thanks for the answer and detailed explanation, I will try to check if the voltage is coming to the connector as you already said. If I manage to solve the problem, I will report. with respect, kind regards ☺️
