I have a 2006 Dodge Ram 1500. The Check Gages Light goes on & stays on after I drive for 15+ minutes uphill on steep roads. None of the other gages (temp, oil, etc. show any problems). The Check Gages Light will usually turn off around 24 hours later after decending the steep roads. The Dodge dealership could not find out the source of the problem without additional expensive and lengthy investigation of my truck. Any ideas or suggestions???

 

What codes did they pull ?

 

Sounds like your low on some type of fluid. Brake fluid, coolant and washer fluid are the main ones. I'd check your washer fluid.
Wouldn't you just want to kick the dealer for low washer fluid...lol

 

My boy friends 2006 Ram 2500 4x4 bighorn edition, check gages light would come on when he put the pedal to the floor and then the oil pressure gage would drop to 0 and the only way to get the gage light to go off was to pull over and turn off the truck for 10 min or so. The last time it had this issue was right before the trucks piston rods broke into hundreds of pieces. Yes He checked the oil and other fluids reguglarly. The computer code said mechanical engine failure

 

I've seen a check gauges light come on from oil in the pan missing the pick-up on hard cornering, I'd suspect it could come on from climbing a hill too....
