Low Oil Pressure Warning
Hi there:
I have a 2011, F-350 Lariat FX4 truck with less then 1,000 miles on it.
A couple of weeks ago, I started getting a Low Oil Pressure warning light on the LCD display. I took it in to my dealer and said it was a know problem and refereed me to Special Service Message # 21405.
I'm now getting this error message multiple times a day. The dealer as had the truck for four days and have not been able to reproduce the problem.
Just wondering if anyone else as experienced this, and if so was ford able to resolve it.
I have a diesel 6.4L 4V V8 TV engine if that helps

I am a little confused. You say your truck is a 2011 but the engine is a 6.4 L. The engine in a 2011 is 6.7 liters. In any case, I would be wondering why the dealer has taken 4 days to solve the problem. Was the low oil pressure light on when you took it in?

I got the low pressure warning 1 time when I had the ignition on but did not start the engine for an extended period of time, like 15 minutes or so.
I told the diesel tech. at my dealer and he told me to not worry about it, common on an engine that is not running.
I've never seen it on my message center with the engine running. Oil pressure switch is most likely the issue unless you got a 6.7 that did not have an oil line installed on it. There were a few that got away but not likely, who knows.

Yea, I mentioned this to my dealer when I took it in but they couldn't reproduce the issue and there were not any codes. It had happened once at that time.
Happened yesterday (took a picture of it).
This is when turning on the key, waiting for the diag check cycle after the 4x4 message (standard display) and then that low oil pressure light stays on.
I just turn the key off, wait and start the process over and it doesn't reappear.
Maybe the new computer update will fix some of these bugs IF they are even bugs.
If it was normal, it would occur each time and not sometimes.

The new CAN bus network has extensive redundant error checking and clearing. If the light came on and then didn't reappear, the on-board diagnostics would have gone through a redundant check the next three times the truck is driven/started and if passed, cleared the DTC permanently. Even when a DTC is reset manually, the truck won't officially clear it until the redundancy is perfomed by the on-board diagnostics.
Now if the light comes on an and off intermittantly, that info should still be available in the memory for the technicians to to download and analyze. This is to help technicians and customers solve gremlins that only appear when the customer is driving with nobody else around. The old technician argument of "I couldn't reproduce the problem" should be a thing of the past - technically.
