I have a 2015 ram ecodiesel. I was recently going on a trip and got about 30 miles from my destination when I decided to make a quick pit stop. Truck was running fine. Then it started saying no oil pressure when I started the motor back up. If I gave it fuel the oil pressure would go up and the light would go off. I went ahead and limped it to the destination but every time I’d come to a stop it would alert me for no oil pressure again. It also felt like I had lost a lot of power but no other engine lights were going off and all the other temps read correct. I only have 50k miles on it. Any help I can get to determine the issue would get greatly appreciated. Thank you in advance.

As I understand it the oil presure indication is a computer generated value not an actual value.
You could install a run tee were the sensor is and screw a mechaical guage in along with having the sensor hooked up and see what you have.
If you actually have zero oil pressure I'm afraid you on on a quick path to a new engine,
hopefully it is a bad sensor and incorrect computer generated signal.

Check your Oil Cooler, It runs under the intake plenum, you should see a visual leak running down the back of the block.

New motor was the result of my issue. Good thing it is covered under extended warranty. Fiat Chrysler put an extended warranty on the motor for 120k miles or 10 years for this reason. They also put an extended warranty on the exhaust for 70k miles. I don’t recall the years though.

Back in the day when your oil pressure dropped to zero, you stopped driving it until you repaired it. Not I limped for another so many miles. WoW.

Seems constructive to advise other readers of this thread to stop driving if no oil pressure. Wouldn't want folks to think it is OK to drive with no oil pressure. Good is debateable but it was an "or" statement. :)

A new engine at 50,000 miles, wow! Is this a common problem with the Eco Diesel?

I have a 2018 with 30000 and the dealership is replacing the engine. No Oil pressure, light coming on and off as the pressure went from normal to zero and a loud knocking noise front the engine. Hopefully the new engine last longer. It’s still under warranty.
