P0720 Changed conductor plate
So I've got the p0720 code, I already changed the conductor plate but it's still flashing the code. Speedo works as does speed via livedata.

Any ideas? TIA

Did you installed a used one?? Genuine reman??? Did you send it out to get repaired??? The vehicle speed is based off the values of all the wheel speed sensors and that is done in the ESP/ABR module. Is your transmission in safe mode? What module is the codes set in??

New dorman conductor plate
I believe it is in safe mode, I only have first and reverse
I'll check with a better scanner later on today to see what module the codes are set in

Well I went to scan it today and there were no tcm codes. Engine light is out and it's no longer in safe mode, maybe it just needed some time

It's back in limp mode again!
​​​​​​
I was able to get some tcm codes this time:

P2400 - the right rear wheel rpm signal sent from the traction system via the CAN bus is implausible

P2402 - the right front wheel rpm signal sent from the traction system via the CAN bus is implausible

P2430 - the wheel rpms from the traction system are not available on the CAN bus. (CAN timeout fault)


​​​​​I know the right rear wheel needs a new reluctor ring

If it helps anyone, the problem ended up being corrosion in the plug of the front right wheel speed sensor
