“Low Oil Pressure” In Message Center

[Deercampcrusader]

I’m experiencing intermittently the message center displaying “Low Oil Preassure” and the actual gauge needle being at L after the truck has been started. The check engine light will also come on. Most of the time this does not happen and the oil level is actually fine. I don’t notice any ticking or anything sounding out of the ordinary. Could this just a a sensor issue?

Thanks

Welcome to the site.

Could be, but the safest action would be to see what the true oil pressure is with a mechanical oil pressure gauge and go from there.

Are you sure you have the correct viscosity oil and a high-quality oil filter (such as OEM Ford Motorcraft) installed?

Cheap, aftermarket oil filters can cause oil starvation at start-up.

Easy enough to swap in a motorcraft filter. And like C5 coupe stated keep the viscosity no more than 5w30. You didn't give year, engine size? What is it please?

I dug into his profile, it says 2004 so we're looking at a 2-valve. But that's only part of your question..

Please describe oil level 'actually fine'. Do you check with engine on or off, hot or cold, and where on the dipstick does oil level fall? Does it burn and/or leak oil otherwise?

I think some of the 04's were 4 valve. Just as some of the 03's were..at least thats what my manual states. Always running into the 4 valve section on accident

It’s likely a 2 Valve, 3 valves weren’t used until the 2005 MY in the expy. Being an 04’ it could be a 4.6L as well...

Oh well, that's good to know. I thought it was luck of the draw on the 2003 and 2004 whether you got a 2v or 4v and I figured I was a lucky one! Wonder why it's in the manual - is it a navigator thing?

Yes sir, the 4 valve was available in the Navigator until the 3 valve replaced both the 2&4 valve engines.
