just bought my first cummins after owning powerstrokes and a duramax. like it so far but having issues with the tire pressure monitor, it wont go off even with the correct tire pressure have driven it for over 40 miles and still wont reset itself. anyone else run across this?

Hoss

What pressure are you running front and back? And do you have the TPMS set on light load or heavy load?

Hoss

Oh yeah...WELCOME!!

65 front 70 rear its set on heavy load flashing right rear is low but both rears have same pressure in them? go me puzzled

you have to put in tires what door says for heavy load. I run 55psi in front and 65 rear, you have to drive over 20mph for 10 minutes for it to reset sensors.

thanks guys! ill drop pressure and give it another shot

Hoss

That sounds right. As long as you're above the psi on the door it shouldn't be giving you a low pressure warning. If driving around doesn't reset it then you make have to take it in and let the dealer look at it.

Just double check the numbers on your door for light and heavy load and adjust accordingly. Hopefully that solves your problem.

jacked up the pressure to the #'s on the door and it worked . thanks for the help!

Good deal, they normally give you about 5-8 either way for tempature change and shouldnt trigger light.
