This past Sunday when driving on the road with a lot of small potholes note that my tire pressure light come on. Just the light no beeps. When I got home checked the tire pressure - 36 on the back tires, 37 on the one front and 33 on the other front tire.
Pumped the front tire to have them both at 37 and couple hours later we went for a gym and light was off all 5 miles, after work out started the car and light is back.
Checked the tire pressure - 37 both front and 36 both back, got them all to 37 - no results. Driving couple more days to the office and back - just 4 miles and searched the forum. The light is on but the tire pressure seems to be holding. These are first days in Georgia when we are staying above 90 degrees, don't know if this has anything to do with the sensor or the tire.
Lowered pressure yesterday to 33 all - same result.
Is there anything else to try before going to the dealer? I am not going to have anytime before Saturday and I don't see any damage on the tires, but who knows.
And what you guys think, should I even try to go to someone other place like NTW tires, or just go to the dealer?
Is this seems to be tire pressure sensor going bad?

 

i have a feeling that one of the TPS might be damaged?

 

Thanks. I set an appointment with my dealer for Wednesday and can you believe this afternoon when I turned it on to drive home, the light was off all the way.
I’ve got a feeling its not the end of the story, I’ll see what happens tomorrow.

 

Since my last post tire pressure light behaved pretty strange – sometimes it stays on sometimes it is off for no apparent reason.
I tried to pump some more air, but no result, the only thing was consistent that if it comes on when you start the car than it stays on all trip and if it is off than it stays off all the way.
Today I took it to the shop and an hour later they said that one of my sensors did not transmit properly, but the sensor itself is good and the only thing they did it is “recalibrated the sensors to be set for the secondary set of tires and put switch to secondary from primary in the
glove box”.
I was reading here about that switch and was looking for it in the glove box, but I was on the driver sit and could not see it – it is actually on the site of the glove box when you open it.
I am not sure if I could save $120 by switching that myself, but if it is happens to anyone try that switch first.
