So my tpms light came on last week and after some searching on here, I was able to pull some codes to see what's up. It shows the following

15
16
17
18
21

15 thru 18 are low pressure on each tire

21 is no comm to LF sensor.

Now I can understand if my LF sensor is bad, but why does e
It show all my tires low? I checked and rechecked all pressures and they are all at abot 32 psi

What am I missing?

 

Unless it's just old info logged in from some initialization or something at some point, I'd be more inclined to look at what's common to all four wheel sensors than to consider all four went off simultaneously. Have you tried resetting the whole system and seeing if it resurfaces?

 

Mine is doing thre same thing...it looked like it failed a sensor...so we were going to change it...then it failed all of them...it gets a free trip to the dealer soon...

 

Thanks for the tips, I checked out all 4 corners and visually all look normal and all have even pressures. I saw the steps to reset the whole system, but I'm thinking that I will just make a trip to the dealer. I am covered under the Elite warranty until 72k miles, so might as well use it while i have it.

Yup, same here. Dealer trip it is.

 

Definitely should take it to the dealer to check that out.

 

+1

 

turns out we had a bad sensor(knew that form the tire dealer) ...the dealer cleared the computer and fixed the sensor as well. all good now....

 

Ok, well i'm swallowing my pride and updating everyone just in case anyone else finds this during a search

So I went to get my oil changed at my local quick lube place (been going there for over 10 years)

The same dude that always does my oil chance does his thing, and checks all my other fluids. He then hits each tire with air and and walks over to me to tell me "That yellow light should go off once you start driving, I filled all your tired up to 35 PSI"

I was like "ok bud thanks" but in my head, I knew that the sensors were messed up. Or so I thought.

Lo and behold, I start driving and the light went out.

So who knew all the tires had to be to at least 35PSI?

So Um, problem solved

 

That usually does the trick on my fx... but since iv never pulled the code when the light comes on i wasnt sure if that was the issue here or not. Always best to start with the cheapest possible solution i guess
