Since I've been working in a tire shop for several years, I have a question I'd like to ask. How many of you are familiar with blank, programmable Tire Pressure Monitoring System sensors and the programming tools required to get them to work? The sensors I used one particular week was a Schrader EZ-Sensor 33500 and the tool I programmed with was a Bartec Tech 400 SD running the latest software update. What are yours?
