2D1C Accelerator pedal module, pedal sensor signal 2

Hello!

I started getting this BT-code like a month ago, and now I get it all the time.
Just got home and limp mode all the way, have to do something about this.

What should I change, or how can I check what to change?
Guessing it's the pedal sensor, but is there anyway to actually measure voltage to tell where the error is coming from?

Cheers!

Sometimes I also get tire pressure monitor failure, BDC failure and ABS failure on order they appear. I get the TPMS EVERY time I get the CEL and BDC has shown up 2 times, the ABS failure I only got once.

Some more info:

It wasn't the pedal sensor. Swapped the assembly between cars and everything was the same. My dealer has looked at this problem and it has cost me like 2000 U$ in total and they didn't find anything....they just switched out impertinent stuff.

Anyhow, it seems the problem was cable 7 in the grey subconnector.
Slot 6 and 7 in the small black subconnector seemed like they were glitching as well so I changed them as well.

Now, I just did this yesterday so perhaps the problem hasn't been solved. If I don't post back here, that was the problem which currently seems very probable.
