At first sorry for my language, I'm from Slovenia ;)
Focus 2004 1.6 petrol 74kW
So, I had faulty VSS (speed needle dropping to 0) and I replaced it with new aftermarket sensor. There comes new problem :D The speed needle is waveing/oscilating for about 5-10km/h (attached gif). I tried to replace it with another new sensor (other manufacturer) and still same problem. Forscan did found 2 DTCs: P1000 and P0723.
I already did clean contact, try to find some faulty cable, but no luck.
I also attached PrtScr from Forscan live, if it helps (VSS, VSS_OBD, OSS).This was recorded barely moving.
Any suggestions what should try to fix?
