TPMS light came on again.. rear tire was losing air

rear tire losing air tpms light came on again..
I aired back up to 34psi up front and 35psi in rear
now what? what needs to be done to get this idiot light to go off?

 

recheck and drive it a few miles, if it still doesn't go off, go to a shop with a TPMS scanner to check signal and battery strength.

 

you got a button?

When temperature drops, air pressure goes down. If you're putting in 34 PSI in the tire during the day when it is warm it could easily be closer to 25 PSI at night when the temperature drops. This is a common issue at this time of the year when it starts to cool off.


Or you could have a bigger problem. If the light keeps coming on you may have a slow leak. Get the tire checked.

 

Yes I think one tire has a slow leak the RR it did this before and I did the reset thing by dropping each tire to 32psi did the reset button then aired them back up to 34/35 psi and eventually after driving around a bit the light went out. I don't drive the truck a lot because I have an older corolla that uses far less gas so the Taco sits in the driveway for sometimes a week or more without driving it. So the last time I tookl a longer trip after it was sitting a tire must have bled down enough that sure enough I got only around 10 miles and that darn light came on. Now I check the tires more often which is annoying for sure.

 

At work I just set the pressures above threshold and leave the key on for 5 mins, usually clears itself no tools no buttons.

 

Why don't you get the tire fixed? It's not safe to drive with a tire that could potentially fail during operation.

 

Of course I will.. when time allows

 

Adding more air is for sure the solution, it just hasn’t worked yet. Keep trying! The light is for sure the idiot here! Dig in and you’ll win this battle!


Be an adult and get your shit fixed by a professional, in this case a 17 year old at Discount Tire, they take walk-ins. I’m not going to lecture you about safety.

 

Are you sure you're losing air and your dog didn't pee on the tire?

 

Take it to discount tire have them check the tire for leaks .
