What would happen if the TPMS module were removed?
In theory, The dic would think that there wasn't a TPMS to begin with and may not bother with throwingthe code anymore. You may have to reset the battery by removing the terminals for half an hour or so.
If it still comes up after that, try going to a dealer and explaining that you want them to disable your TPMS completely using a tech 2 and if they are a good dealer, they will do it for no more than a 1 hour rate, still leaving you up $100 from what buying 4 sensors would be.
