Ok, so I unplugged what I believe is the tpms and I still have the low tire light on. Am I missing something?

 

It does not work if you have an 06+ SC. I had same issue.

 

That’s it. I have a 2007. Thanks

 

You can replace the bad sensors and then program them with the Techstream to save money. The sensors will run around $75 to $85, the Techstream about $25 to $50 and installation about $10 to $15 each. There are a couple of threads on this on the forum.
