why are my tyre sensors not activating on cars computer

What is your question?

Had garage put 4 new tyre sensors on my 300 touring and activated them with a v tec tool.Now car shows 000 pressure on three tyres and a bar symbol on front right. Tyres are at correct pressure and I have driven it for over 60 miles. this is causing engine fault light to stay on but there are no engine faults according to my diagnostic tool
