I have had this truck for a month now and a few hours ago as i was coming home the Tire pressure light blinked for a bit then it stayed on steady. I looked in the manual and it mentions system fault and some other stuff.
I checked the tire pressure and its about 40psi all around, i haven't really done anything to them sine i purchased the truck, not sure why the light is on now ? I have driven the truck for another 10miles after i measured them and the bulb is on steady now upon start.


Any suggestions or things to do, please help ?

steady on means a tire is lower than what it should be. if there is a system fault the bulb continues to blink. if you can't find any tire is low then take it back to the dealer. suggestion tho. get a digital tire gauge these things are sensitive to within a few lbs of what they should be. all i can say is get used to checking tires once or twice a month. this isn't just a dodge thing almost any vehicle that is new and has these monitors they are more a nuisance than a help.

 

I agree BenD.

More stuff to go wrong!!

Did you check the spare tire??

 

I agree with Ben D., my Grand Cherokee Overland has the tire pressure sensors and my current tires have a higher air capacity than the stockers. The overhead it not programmable so it goes off under 32 lbs. for too low and at 44 lbs. for too high. My current tires have a max of 44, so when I air 'em up to 40 for a long camping trip to the north Ga. mountains in June for best fuel economy, the overhead went off constantly as the tires heated up on the trip. Very annoying!
I also think in a 4x4 it would really be a PIA, when you got to air 'em down for off-roading.
There was also a couple posts on one of the Jeep forums where the sensor went in one of his tires and the dealer wanted like $185 to replace, so it's that or having to look at the light going off in your face forever!

 

So i guess the suggestion is to get a digital tire gauge and measure them after work today. What should they be about 35PSI, sounds and looks low ?

Also how long does the tires need to be standing for a accurate cold pressure measurement ?

Thanks,
Pete

 

all 5 of mine are set for 42 psi.

 

Check the Tire Pressure sticker on the drivers door, and stick to it(sorry for the pun)

A side benifit to a nitrogen fill is that Nitrogen expands less than straight air, this is crucial for us with TPM's, less checking/adjusting tire pressure on long trips and less flashing TPM lights. Just don't let "Goober" at the Tire store put those "Green Caps" on your TPM valve stems.

 

can you pull a fuse? pull a bulb?

 

Its a brand new truck with stock tires and wheels it should work properly, i don't think i need to be pulling fuses at this point yet..lol

The door sticker says 35PSI, but yet it seems everyone here runs them at 40PSI or more are they referring to cold pressure ? Will that make the stupid light turn off, or is that too much PSI ?

Thanks
Pete
