Hello,

I have a 2010 F350 Super Duty with a 6.4L diesel motor. I just recently experienced two instances where my truck randomly shut down while driving. When it happened, I had been driving it for about 15 to 20 minutes or so, and when the engine shut down, the oil light illuminated immediately. The first time it happened, I happen to be entering a shopping mall and I was able to coast in and park. The second time I was picking my daughter up from daycare and I had to pull off to the side of the road in the middle of heavy traffic and park. Both times I was able to get it to restart the engine again after letting it sit for about 2 hours or so.

I have done some extensive reading on what it may be and at the point I desperately need some professional guidance on what to look for. I have reason to believe it’s related to oil pressure or maybe a temperature senor of some kind. I just purchased the AutoEnginuity with Ford Enhanced package and have been doing what I can to read failure codes and watch various system monitoring. Any guidance on diagnosing this problem at this point would be greatly appreciated.

James, when that light comes on like that it has zero to do with low oil pressure. Just try turning off the engine, then quickly return the key to the run position. That oil light is on because the engine is not running.


To your question. Did the check engine light stay on after the engine quits but before you turn off the key?

Is it still on?

Go to an auto parts store and have them read the stored error codes. The stores usually have a list of what the more common codes mean.

Given symptoms and cool down drive again, my guess, sight unseen, is that you have a bad Exhaust Gas Temp sensor.

You have several. Code will tell you which one.

Good luck.

First, someone needs to move this to the 6.4L section....

Cannot the AE read codes? Have you found any codes? Seems to me I have heard of this that involves a chafed wiring harness, but don't remember.

Hope you find some help. I have had 2 6.4s, but neither had that happen--but much worse.

Hi John,


Pulled my truck around to my little garage and ran the codes again and got this:

P1184 engine oil temperature sensor out of self test range

From my understanding this is indication of a bad oil temperature sensor. I purchased a new sensor from the ford dealership and am about to dive in to replace it tonight. May not be THE problem but am going to tackle this first. I also purchased 3 Gas Temp sensors and will replace those next after the oil temp sensor is replaced and run codes again. What are yout thoughts?
