Installed TRD valve stem caps, months later TPMS on

Hey Guys,

I installed these TRD valve stem caps (with locking nut) that I bought from a member here, and now months later my TPMS went off. I just refilled all my from 30 to 33 psi, and it still is on. When I turn on the truck it turns on, then turns off for a second, then turns back on and stays steady.

The valve stem caps are the only things I have changed in a while and when I came back home I took off the caps and put on the original ones and reset the battery for 20 minutes hoping that it would reset the tpms... however the light is still on.

Anyone have the same issue? Any advice on what I can do to get this fixed? I attached a pic of the stem I installed.

Thanks

 

Be careful with those valve caps.... One of my cap's logo came off and it looks like this:

 

x2 lol

 

No I didnt.. I never knew the spare had a tpms.. I will check that next thanks

 

Thats normally the one that goes off. If your lucky your spare will be valve stem down if not drop it and put it that way. My tpms went off last month and I filled the spare, problem solved.

 

Thanks guys I will try this out and cross my fingers!

 

They were down to 29-30 psi all around. I usually keep them at 33, with a tire max of 35

 

You are honestly, truly inclined to blame a TPMS light on a 3-month-old installation of an aftermarket valve stem cap?

 

I ready somewhere on here a while ago to beware of those trd stems because they could mess with the sensors, so thats why I thought my light went off.. But at the time I just installed and locked in and said eff it I am going to keep them on especially because the light hasn't gone off yet.

 

But the picture of what you installed is of valve-stem CAPS, not a valve stem, from what I can tell. How can a valve-stem CAP cause air to leak out of a valve stem?

 

Also, constructively, the first thing I did when I brought my truck home from the dealership was to drop the spare and flip it upside down, so you can fill it without removing it. IIRC all Toyota vehicles since 2008 with full size spares will have TPMS sensors in said spares- Tacomas, 4runners, Rav4s, Highlanders, etc.

 

By chance do you guys know they spare tire max pressure?

 

Same as the others...

 

I just checked my spare and the psi was 33 (normal).. I pumped it up to 34 just in case and checked TPMS.. and its still on... do I need to bring this to the stealership?

 

If all tires are aired up then thats all you can do. You will probably end up buying new ones if they arn't under warranty.

 

After reading up on some old threads.. i tried the reset (initialization) button and the light turns off. The manual says to hold the button for while key is in "On" position until the light blinks 3 times...

Glad that the light is off for now, hopefully it doesnt come back on again!
