I had a sensor that used to work only when it was warm but set of an error when the temperature was colder. And being that I'm in Canada it's usually colder LoL!
With that being said I also travel lots and I just got back from traveling for the past year and I think I had another sensor go, so I replaced all 4 sensors with Dorman sensors I ordered from Carid.com

Will the car learn all 4 new sensors or do I have to take it to a tire shop/dealership to have it done?
It's been 3 days and roughly 200km of driving. How long should it take to learn? With start-up all 4 show 400kpa then I get the error message and they show a dash. I know the pressure isn't actually 400kpa either.

 

Were these pre-programmed?
I have seen listings of pre-programmed sensors online that state just that. Yours may have been cheaper (4x) in the case they avoided pre-programming them.

 

I don't believe they were pre-programmed. I've been in and out of so many cars over the last few years I fully thought the system would learn the new sensors. Must've been a different car then. So I have to take them to get programmed then?

 

Forgot to update earlier.

But it after a little over a week the system started to learn the sensors bit by bit as in they’d recognize a new one every day. Took 3 days for the last one to finally be recognized. Had 1 days where I still got an error randomly but none in the last 2 weeks so glad this is working properly, without needing to get them programmed.
