So one of the sensors has gone out in my wife’s 2009 gx. Yes I’ve checked the spare and the 1st/2nd tire set button, however she wants to keep the tpms system working so I can’t ground the wire behind the glove box. So what’s going to be my most cost effective way to get this done. The threads I have read say either Toyota dealer or discount tire has the ability to fix it but these are a few years old. Just wondering if there is a DIY way or if it’s easier to just bring it somewhere.
