Air Pressure Sensor Q21-1041 150 PSI for PETERBILT KENWORTH FREIGHTLINER VOLVO

hey guys so i thought to help you guys out um if you clicked on this video one of your gauges is not working properly and this is what my gauge is doing when i'm driving sometimes when i'm stopping it's just messed up so and i'm not actually losing air it's just the gauge is not working the pressure sensor so i have the pr i bought a pressure sensor it was a 140 canadian dollars something around there it's a little sensor has the three clips in there that's the part number if you want to know this is uh this is for the rear air pressure tank which is right there now it's working right now but i figured out which one it is so what you want to do is drain all your air then what you want to do or you could do this first take off this cover this cover that goes on here there's a one screw up here one here and then there's one all the way down here so you have to move the carpet for that so
