I just got done checking the pressure in my tires, they are all around 35-37 PSI. But the msg wont go away. Is there some sort of reset that i should be performing or am i seeing some sort of issue coming to light? It did it once last week, i filled the tires up and it went away. This morning, i got in to see that it was back, and wouldn't go away with a few psi added to them.

 

You might have a sensor going bad. Try turning the key on (do not start) and then depress the accelerator pedal three times. Not real fast like you're trying to juke a old carb'd vehicle to get it started, but all the way to the floor, then back up, 1/2 sec, down again, etc.

 

Mine lit up last week for the first time. Went and checked and they were all at 32. Filled them all up to 35, and when I started it up - the message and light were gone.

 

I think there is a Tire Pressure Sensor in the spare tire too. Might want to check to make sure the spare isn't low.

 

The individual TPI readings for the 2010 is one feature I hope we see a software update for our 2009s. I had one go bad 2 weeks after buying the RAM and it took a visit to the dealer to get it fixed.

 

my light comes on every other week. pain in the aas

 

Yeah, my parent's Grand Cherokee gives individual readings of each tire. I was stunned when I realized that my nearly 50k Laramie just flashed 'Low Tire Pressure' with no specifics... I was bummed.

 

got the same message on mine last week, lowest pressure was 32#. it was the first cold weather (50F) for florida this year, though. filled them all to 40#, message went away.
