I just had my tires filled on my Toyota [prius](/topics-prius/), when my pressure check light wouldnt turn off I tried resetting my car. Maybe I’m doing it incorrectly because it isn’t going away Mechanic's Assistant: Have you checked your tire pressure? Do you have a tire gauge? I don’t, but as I said I took it to a mechanic this morning and they filled it and checked it Mechanic's Assistant: What year is your Prius? 2007 Mechanic's Assistant: Are you fixing your Prius yourself? What have you tried so far? I turned on the car without the [engine](/topics-engine-toyota/) and proceeded to press the reset button below my steering wheel but my pressure sign started sort of sputtering but not disappearing Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? No, thank you though!

Hi Ron, I'm Mads, I'm having difficulty with my 2007 prius

Hi Mads. Nice to see you today! I'm sorry to hear you are having this problem. I know this can be frustrating. Please give me one moment to type out some information for you. Sit tight one minute... I'll be right back! Thanks for holding, Mads. The tire pressure warning reset button is located below the driver's side dash. The procedure you are using 'is' the correct procedure. If the light is not resetting, this means there is a problem somewhere in the monitoring system. Very commonly here is a faulty tire pressure sensor. There is one located inside each tire, as part of the valve stem assembly. If you just had the tires replaced, there's a strong chance the sensor was damaged during the tire replacement procedure. These pressure sensors are extremely touchy. The slightest jar can harm them. To figure out which pressure sensor has failed will require the use of a scan-tool that can read the outputs from these sensors. Once found, the tire is removed from the rim, and the pressure sensor replaced.

in the meantime as I make preparations to see my mechanic to replace this sensor; I am safe to drive on my recently filled tires? The light is simple a result of a sensor malfunction?I haven't had them replaced, but recently filled and pressure checked

Absolutely perfectly safe to drive the vehicle. The pressure monitor is strictly for driver information. It plays absolutely no role in any other systems what so ever.

It is an incredibly rainy day where I am located right now, With traction occasionally flashing briefly I just wanted to make sure I am not going to get a flat on the road. So in your professional opinion you believe I am safe? (Apologies I am simply concerned for my car and safety)
