I keep getting a low tire light, and the guys at the dealership believe it's a faulty TPMS sensor in my spare b/c my tires are fine and pressure is correct. Is there a fuse I can pull, or is the sensor in the tire reachable that I can pull it from there? Just trying to figure out how to fix this for free, if possible. Thanks!

 

Pretty sure there isn't a sensor in the spare

 

^^ Correct. There is no sensor in the spare tire.

 

Try these steps:

1. Find a new dealer. Your dealer is simply clueless. There is no TPMS sensor in the spare as has been stated above.

2. Reset the TPMS System. It's clearly spelled out in your owner's manual. If you can't find it, or you have no manual look here:

1. Only dealer in Austin.
2. Muchas gracias, Mr. Lou! I'll take a look!

 

^^^^When I was working I used to travel to Austin on Business. I went there 5 or 6 times a year, I had a client there. I luved the BBQ there from the County Line. I'd go and we'd order the Cadillac. What a feast. I luved the beef ribs. It is the only BBQ place that I've ever seen that threw away every other rib bone so the ribs remaining would be really meaty. My mouth is watering.

Hard to believe that in a city that large that there is only one Lexus dealer

Mine will do that if you toggle the switch . There is a primary and secondary. If I swap it to the secondary the low tire light comes on. Swap it back to primary and it goes away. I don't know why it does that.

 

That's for your second set of sensors if you have a winter set up or just another set of wheels with sensors on them, you register those as your secondary set.
