You can get aftermarket sensors like the ITM Uni-Sensor. Less than $100 for the set of 4 on eBay, and they come pre-programmed, so no need to buy the $250 scan tool
How does that work? some type of cloning sensor?
Also how do you realign the sensors with the locations when you rotate tires..
There is a black hole where information about this elantra tpms system should be.
Previously all my vehicles were either jeep with autolearn
or dumb systems with tpms idiot light that didnt need to know which sensor was in which wheel position.
afaik the elantra system doesnt autolearn sensors(ID) or update sensor locations automatically when rotating etc.
edit: I'm not seeing any ITM uni-sensor for anything after 2017 elantra.
