tpms

Asked mechanic to replace 5 TPMS sensors - he did, light still on - found out today I have a donut spare and there isn't supposed to be a sensor in it - if I have him remove that sensor, will the light on the dash finally go out? I have an 09 Jeep Liberty Sport

Hello Newbie here Picked up a 2007 Liberty sport v6 auto 4wd. The previous owner installed alloy rims and tires from "he said" a 2008 Cherokee, however they look a lot like my Wifes 2008 Nitro rims. Both mopars so one would think the tpms would be the same, butttt we all know ma mopar did some...

my TPMS light came on tonite, i checked all the tires and their pressure is fine. today is the coolest day 59 we have had this fall so far. does anyone know how to reset it before i give up half my day running it to the dealer?
