My Tire pressure warning light will not go out??

I had this happen when it was under warranty....they replaced the contraption underneath the steering wheel because it was some electronic issue...tire pressure was fine (and we can still do a manual check).

Do you know if their is a fuse to shut off the idiot light? I'm with you.....just ignore it

 

Did you try the tire pressure warning reset switch below the steering wheel? Instructions in the owner manual. BTW, most here recommend at least 40psi in the tires for better MPG.

There is no fuse just for that system as it shares power with others. It's better to have it working properly.

 

If you just got new tires, it's possible that the tire shop damaged one of the sensors or a coincidence that the battery in the sensor went bad at the same time. If you know the tires are fine, I wouldn't worry about it right now as the TPMS isn't an integral part of the vehicle. It'll still drive and do everything else just fine, you'll just have to tolerate a light on the dash.

 

+1. A few months ago I got early warning from the TPMS when a screw got buried in one of the tires and caused a slow leak. Without the TPMS I probably wouldn't have found out about it until much later when the tire would go almost flat.

 

Don't have a Prius but have 2007 Avalon, since buying car new the light has always been on, never could fix it even under warranty, stayed on forever. This weekend need new tires went to COSTCO, was told if they put 4 new tires on it can not leave there with that light on. Said sensors cost about $73 a piece if defective. They had me pull the car around, they used a sensor they just touch the tire with and it instantly told them the tire pressure and if the sensor is good. They inflated all 4 tires to exact pressure and all sensors were good. They then checked the SPARE TIRE, it was low and that was what caused the light to stay on. Replaced tires, no new sensors needed, filled up my spare and the light is now out for the first time in 5 years. So try checking spare tire pressure, or if a COSTCO take it to them and they will check it for you for free. Good luck hopes this helps.

 

Wow, did you give them a tip?
