I would like to know can anybody out there give some information on theses tire sensor's so on my 2013 Durango I'm getting the light on my dashboard blinking telling me that my air pressure is low on my driver side front tire so I put air in it so long story short it keep happening off and on periodically then I noticed another light on the dashboard with the first one so I check around and found out that was the sensor it's self and says on all the time until it's replaced so I go buy one for $30 then had to pay a tire shop $35 to put it on and now the dashboard is telling me it's the back drivers side tire and I know that sensor it fine so I'm wondering could it be glitch in the computer system in the car because I talk to one mechanic and he told me you have to change all the tires at once and that's crazy that would the around $350 and I ain't got it like that and my other problem is the Forward Camera in the front bumper that light is on in the dashboard too it's telling me it is dirty I have washed that thing the best way I know how but that light stays on all the time and that part is$500 or so I ain't doing that either so does anybody have some help for me because I'm on a Budget Help me please......BG
