low oil pressure lite

[slyrydr]

so i'm driving along empty, get a pull over as soon as possible warning, so i do and the engine shuts down, warning lite says low oil pressure....wtf...so i get out and check the dipstick, oil is full....get back in, truck won't start...hitch into town, no cell coverage where truck quit....get tow truck, back to my truck, turn on key, no idiot lite/warning, so i start it to get it to line up with tow truck bed, works fine....take it to dealer...waiting to see what they say.....any body with experience with this?....

the dealer discovered the problem....the nox sensor in the exhaust had a short in it which automatically shut down the engine, resulting in the low oil pressure lite being illuminated, as well as the check engine lite and a couple of others....when the incident happened, the "voice" said to pull over to the side of the road as soon as possible, safely, of course...as i did so, trying not to get into the snow too deeply, the engine automatically shut down at about 10 mph, resulting in the low oil pressure lite....as i was concentrating on vehicle management with no power steering, i didn't get my eyes back on the dashboard until i was stopped, then seeing the low oil lite, i assumed that was the cause of the engine shutdown....but it was just the nox sensor, easy fix, no other problems..

Just had the recall for the NOX sensor replace/or recall ration done two weeks ago. Talking to the tech it seems some of the sensors did not take to the 400/800 programming and either fail or will fail eventually without the upgraded software. The dealer will replace the sensor if it has triggered any codes 34000mi and no codes so I got a PCM update and a TCM update. Drove like crap for a day until the tranny "relearned" again. Have put 2200 mi since then an no problems.

I just had this happen to me! Shut down warning, then it shut down. No oil pressure, but crankcase is full. It's sitting at the tow yard currently until Monday. I just had the NOx sensor changed about 3000 miles ago.

Did it say no oil pressure once the motor quit running?

Thats odd, the C&C trucks do NOT shut down for a NOX sensor failure... nor should they...!!!
NOX sensor failure should only derate engine, NOT shut down. Have had multiple NOX sensor failures on my C&C truck, only derates, does not shutdown.

This is why I'm unsure about the new trucks. Don't like the fact they can shut themselves down and just not crank. Even if it is to try and protect the engine.

My truck was showing no oil pressure before it shut down. Checked oil and it was full. I have had NOx sensor problems.
