what is the correct air pressure to get this light to go off? I have an 08 2500 4x4 4 door short bed. Any help will be appreciated.

65 psi on all 4 wheels. Make sure they are very close as well. I've seen mine trigger if 2 psi difference.:doh:

I have 60psi in the front and 45ish in the rear w/ the light load button and no light. Look on your lower B pillar (when you open your driverside door) for tire pressures w/ light/heavy load pressures.

You can only set that AFTER clearing out the locked in TPMS lamp. I just had to this morning. :doh: I'm gonna lower to the 45 today when I leave work. The procedure on the other thread explains the steps. Next they will have us sacrificing chickens to clear the darn thing. :banghead:

Dam finiky TPMS. I went to reset to light Load with 65/50psi. Wouldn't do it. Then tried again later this time set right at 60/45 (label settings). Reset to LL perfectly. :confused013:

for the record put 70 in the front and rear today and no light. AMEN

Yeah Dad, as you've documented on here in the past, these sensors are pretty picky. I was talking with one of the techs at the local dealership and was told that the tolerance for setting the dash light off or the light load switch on was only +/- 2 or 3 pounds. I wish the dealer was decent enough to reset the parameters for the sensors for me, or someone puts out a programmer that will.

:hehe: I can't stop laughing at this! Read the last sentence over and over again slowly. I'm sorry Dad but why would you NOT do what the owner's manual or the door sticker tell you to do? Guys, these things trigger at +/- 2 psi! You need to be right on what the factory states for the tires unless you get someone to alter the parameters in the ecm. The system sucks we all know that, but of course the the cel will trigger if you aren't following the prescribed settings.
