1999 Dodge Ram 2500 Diesel Chech Gauges light.
I have a 1999 Dodge Ram 2500 Diesel. The check gauges light came on the other day, along with oil pressure gauge not working, as if the truck is off. the truck still runs fine, no chugging or anything. Maybe Oil sending unit. anyone come across this before?

The oil pressure sending units on these trucks (and many other vehicles) just suck. Try swapping it out, and see what happens. If you are still getting zero pressure, put a mechanical gauge on it, and see what IT says. If you still have zero pressure, stop driving it, and find out why.

Captain
If the oil pressure gauge drops check gauges light will come on it’s supposed to do that. You either have A no oil pressure Or B a faulty sending unit/short in the wiring. Hope for the latter of the 2. You can always have a shop hook up a manual pressure gauge and get a true reading. My old 98 has a short somewhere I need to address. Oil pressure goes to nothing when you hit a bump just right and check gauges comes on ding ding then right back off again. Hooked up a manual gauge to it and pressure is steady so I’m not worried. Low oil will cause it to come on if you get in a weird angle or turn really sharp from the oil pump sucking air for a second.

You'll only see the "Check Gauges" light when there is a gauge indicating a bad condition. It's a Master Caution light. There is nothing wrong with the gauges ... they're trying to tell you that there's something wrong with the truck. Asking why you're getting a "Check Gauges" light is like saying, "I have a 'Check Engine Light' ... what's causing it"? We need more information.

That's not completely true. Check gauges light can come on if there is a problem with the gauges. Every so often I can start my '05 Hemi 1500 2WD, and the check gauges light comes on and usually the oil pressure needle hadn't moved. I shut it off, restart and immediate oil pressure and check gauges light is off. This would not be an oil pump or oil level issue, and not a wiring problem, so only thing left is oil pressure gauge issue.
