2019 w/20K miles 1st owner..

Driveing after 10 miles . Came to a stop and the low engine oil pressure warning came on..Looked at the gauge and NO OIL PRESSURE READING. As soon as began moving - all went to normal , stoped and warning came on again - Stopped put into park and all went to normal, into drive warning again .. started moving all normal.

Oil level fine .. all service by Ford.. BTW they have NO IDEA.

Any thoughts

This seems to be a common issue:
I had my oil pressure switch replaced last spring, and I have not had the issue return since.

Thank you... Interesting as it's not a "happens every time" issue. I would think that if the pressure switch were "bad" it would be all the time.

Appreciate your post

Thank you for the links.....I might have put this in the wrong area - if so please move. Merging all might be a good idea. Do seems to be some common thinking that the sender switch might be the cause ? Right now the dealer has no idea(s) no codes were thrown. I was just bragging how this has been the most trouble free truck I have ever owned

Rodney - I'll been closely watching all of these threads, as I find it hard to believe that there is such a high MTBF (Mean Time Between Failure) rate for something that is an oil pressure "switch" and not a sending unit to an oil pressure gauge.

Some members have had the switch replaced and the problem has gone away, while others have had it replaced under warranty and still have the issue = read thru the other 3 threads for details and you can do you own count

As I mentioned in a previous thread, I wouldn't expect to see this to be caused by engine design, as this engine has had a long history with JLR (Jaguar/LandRover) prior to it application in our F150s, but Ford did redesign both the oil pan/sump and oil cooler for the F150, so I suspect those new pieces added to the existing engine design is the cause, but I have nothing empirical to prove this.

My personal opinion is that I don't think it is the oil pressure switch nor the oil being used but a combination of those new parts added to the existing block creating a low spot where the pump momentarily runs dry causing this condition.

I'd be interested if there are any vertical baffles in the oil pan underneath the large horizontal V-shaped one covering almost the entire bottom of the pan:

All makes sense - BUT my question(s) would be
  • should this have been happening DAY 1 - on all 3.0 if Ford has created this with a new design ?
  • where do we go from here ?

Rodney - 100% agree with you, but not sure I can answer either...

Only way to get Ford's attention is to bring it in for service and ask your dealer's Service Manager the same questions:
  • I'd be interested in what DTCs are thrown in FORScan
  • You may want to mention you are a member of this forum and other owners are experiencing this similar issue
  • It's only until enough of this same issue get reported and accumulated in their national database will Ford react

Rodney - perfect!

Please report back what your local Service Manager can find out from Ford on this issue.

Just heard from Ford..... The reply from Corporate was to replace the oil pressure sending switch and part of the pig tail. The dealer cannot get the truck to misbehave, but I have iPhone videos that I showed them.....They do not believe that its mechanical --

Rodney - Wow! That was fast turn-around time!

Thanks for posting back with what Ford Corporate's directive is.

So I learned today that oil pressure "switch" = Oil pressure sending switch = where computer get oil pressure value

Based on membership and posts here, I still think the MTBF rate for this oil pressure sending switch is way too high for a brand new part, unless their is a design flaw in the switch itself.

I will VERIFY exactly what Ford is "replacing" I will also get an answer to " is this a best guess " or do we know for sure that the replacements parts are going to correct the issue... Since no code was present - might never know 100 %

Will get the truck back tomorrow afternoon.......

Interesting that you get a message in the IPC (Instrument Panel Cluster = 8" display between speedometer & tachometer) but you don't get any DTCs in FORScan
= Almost acts like an analog gauge with message in IPC
= Gotta believe that this signal goes thru computer => I'm going to find PID in FORScan to monitor
= No DTCs will make it difficult for Ford to diagnose

Thanks Rodney - that does look pretty ominous in red (not amber) filling the entire IPC (not an amber icon) = I take that as very serious and requiring immediate attention/response. Even the DPF full message is only in amber...

I agree with you: What does Ford expect us owners to do with such an warning? Ignore it?

It will get you FULL ATTENTION... It will be an interesting conversation w/Ford today. I farm for a living and have been around equipment of my life. I really dislike the electronics that modern tractors / harvesters / trucks now have . Its great when they work , but often are not trouble free -( I use the Sears refig 1965 model in the shop that just runs vs the GE 2015 in the house . We know the GE tech on a first name basis )

As for the truck I think its electrical :
  • Intermittent
  • will go away by only moving shift to park or neutral
  • warning says LOW / Gauge shows ZERO
  • only at a full stop -
I will report back...........

Oh, I just noticed the red icon and ZERO reading for oil pressure for the first electronic gauge in the upper left -- that also does not look very reassuring = would make me think I have no oil in the engine. And by intermittent, you are saying that you clear this message and it pops back up at the next stop light? Yeah, this is not acceptable....

Thanks for digging in on this one...

It comes and goes ...allways at a dead stop after 4-5 seconds -- take your foot off the brake and warning goes away - oil pressure gauge reads normal ....

Ford cannot get the parts for 2 weeks-- the service manger assured me this is electrical not mechanical I hope he right.

PS I have video that shows this happening ...just cannot post video ( or I dont know how )

did not answer your question - I do not CLEAR THIS - goes away on its own as soon as I begin driving (the oil pressure condition goes away )
