One of my tires on my TPS seems to have an issue.
When I first drive off, all 4 sensors are reporting just fine, but most days after a bit of driving, the little warning triangle goes off and one of the tires is reporting nothing. just a blank where the psi should be.
After I turn off engine and then restart the car, it reports again for awhile
I have checked the tire and it is fine.
Bad sensor? Or?

 

your sensors are going bad, the others will follow shortly. theres vendors in the marketplace that sell tpms at a good price.

 

I can tell you from experience that you better buy original sensors. I bought universal sensors last year and i had to purchase new ones this year as 2 of them were not sending signal. This time i bought those who fit the car made by Schraeder.
