Ghost TPMS Light

Yesterday my TPMS light came on while I was driving down the road. My first thought was that it was just the fact that we have has such warm weather down here in Texas for the last week or so and this particular morning was rather cold. Later that afternoon I noticed that the light was still on. I just got the truck back from the stealership for it's 5000 mile service so I thought it was odd that any of the tires be low. Fearing that I might have picked up a nail I checked all four tires when I got home and found nothing, so, I checked all 4 tires pressure, and then the spare, put 2lbs worth in one tire, and reset the TPMS. The light went off. Less than two minutes later the TPMS light came back on as I was driving around the block. It was getting dark at this point so I thought I would just go ahead and let it sit to see if there was a tire with noticeably less air pressure by morning and then I would know for sure whether it was a slow leak or something else. When I got into the truck this morning, there was no TPMS light, and when I drove around at Lunch, again, nothing. I never reset the TPMS after it came back on the second time, nor did I change the air pressure in any tire. What's going on!?

 

DA#$IT!! and i thought my prob was a PITA!!!!!

 

check the air in your spare........i guarantee you its the culprit.

 

I already did.

 

oh, sorry,i missed that.

 

I haven't had a single problem today. I'm mostly confused why after I reset it last night and the light went off, it came back on just two minutes later, and then wasn't on at all today.

 

would anyone know what frequency the TPMS are on? I guess it could have been some sort of interference, like from a bluetooth device or any number of other things.
