I assume the procedure for TMPS sensors is the same for explorer 2017 XLT or your ST.
Do you know what could be the issue with the following:
- I have 1 bad TMPS sensor which car detects even after swapping wheels front to rear;
- I bought 1 new sensor from Ford dealership who was using my VIN to make sure I got the right one (F2GZ-1A189-A);
- Before installing sensor to tire, I went to one shop and they tried to read the signal from sensor but failed;
- I went to dealership and exchange it to a new one, tried to relearn it using grey tool + retrain mode. I managed to do it for first 2 sensors but the third one which I am trying to replace I tried new one and it did not work.
I read other forums and someone suggest to use OBD tool + forscan to remove existing sensors and try from a scratch (I have FORScan ELM327 and some old version of app itself)
