Whats up guys? Trying to figure out what the problem is here, but I recently got a check system on my display and there is a "!" in a right triangle on teh right side of my dash and a yellow (_!_) on the left (tpms light).

About a 2 weeks ago I had a new set of rims (19s) put on my car and a new set of TPMS i bought from ebay. The shop said they were able to set a secondary set of tpms on my car, no problem and everything was fine until today...I got those warnings. I checked my tire pressure and all looked pretty good at 35psi, one was a little low at like 32. I set that low one up to 35 but the lights are all still on.

What could be the problem??
Faulty TPMS? Orrrr TPMS not install correctly?

thanks in advance

 

there is a switch inside the glove box (on the left i think?) to set the tpms to #1 or #2. you sure that's not touched? maybe try to switch to the other set and see what you got?

 

Hey Henry...already looked at that. All good there no one was in the car besides me.

Is it possible the TPMS wasn't programmed correctly and just now (2 weeks later) the ecu is tripping out?

 

hmm, no one has had this problem?

 

Try re-initializing the tire pressure warning system with your desired tire pressure and see if the helps.

 

I was told only toyota/lexus could program new tpms.

 

if you still factory wheels swap em and see if lights go away, if they do then its that you need to hit the switch to the second setting for the new rims, it probally still set to factory tpms

 

not sure if thats the case cuz i drive almost 2 weeks with no lights and i told the tire shop about the switch and everything. Anyway I hit the switch and the light went away, hopefully it stays that way. Maybe somehow it got hit, i dont see how thought

 

yeah hope that's the case then

 

Nope, I just had new tires/wheels put on by a local garage and they reset the tpms just fine.

 

also, don't forget to check the spare.

 

not sure if its the spare since it didnt go on for 2 weeks...then the check system randomly went on.

 

i don't think the spare has tpms in it

 

The spare does have a TPMS as what I was told!

 

want to try take out the spare and drive for 50 miles to test it out?

i have always been looking for the exact answer. on my ls460l, it's clear the spare has tpms. but the donut spare, it has a rubber value stem, vs, metals ones that are on pretty much all factory tpms i have seen
