Oil Level Gauge on 2019 Expy

[Joey Smith]

Today while driving I noticed my oil level gauge would momentarily dip to low and then return back to the middle.

I have not been driving much during this time and got an oil change around March timeframe and have driven only about 1000 miles since then.

I checked the oil and there is plenty so I am not sure what this means.

Right now the gauge is back to the middle again.

Any thoughts?

Oil level or oil temperature? Pretty sure if it’s the one on the cluster that’s oil temp

I would try catching that on camera and taking it to dealer to fix. Possibly and oil pressure sensor malfunctioning

The one on the far left of the top set is oil pressure.

If you are having pressure issues, you should definitely get it looked at.

Same thing, yeah apparently the Oil pressure sensors behind the alternator have been having issues, especially on f150s. Should definitely get it checked though

The oil pressure gauge drops to zero when the auto start-stop system shuts the engine off at a stop. It jumps back to normal when the engine restarts. Could that be what you’re seeing?

This guys good

Ummm...mine doesn’t.

My oil pressure gauge holds steady through the ASS cycle.

Nope! Oil pressure gauge does not drop to Zero/Low when Auto Start/Stop turns the motor off. That would cause unnecessary panic. People would think something is broke. It holds at what ever position it was when it shut the motor off.

If you were looking at the actual pressure on something like FORSCAN or VCM(HPTuners), yes you would see the pressure drop, but the factory digital gauge does not move.

Yes, this is a much better (and more complete) way to say what I did. If you’re in a vehicle with analog gauges (like an XL F150) it will drop on ASS, but the digi gauge doesn’t.

 

[Squark]

Mine definitely does. It takes a couple of seconds after the engine shuts off, but it goes to zero. I’ll grab a picture the next time I’m out.

 

[Joey Smith]

It is the engine oil pressure gauge (according to the manual).

Is this normal for it to glitch to low briefly and then back to normal?

Anyone else see this?

I have a 2019 xlt Max 4x4.

Thx!

Do you have analog or digital? Digital does not move. Sat for over a minute with the motor just 10 minutes ago at a stoplight, did not move.

I have a digital one. Now it is not doing it but I have the AC doing and ASS is not kicking in. Not sure if that is related.

Put it in Eco, it is more aggressive about AS/S.

See if you can catch a pic of it doing it, and get a scanner on it if you have one.

Here's a video of my oil pressure dropping to L when the engine stops:

Looks like somebody was wrong @LokiWolf. That definitely dropped with auto start stop

Outside of ASS it SHOULD NOT drop. A lot of newer f150s are having the oil pressure sensors fail which causes exactly your issue IF it occurs outside of ASS

 

[Joey Smith]

Appreciate all of the responses. This forum is great!

I just drove my Expy while towing my travel trailer to get my setup weighed at the CAT scale. I never went into auto stop start (given I was towing) and also never saw the oil pressure indicator drop.

Will try watching it while not towing to see if that is the main difference.

Again, thanks for all of the input. Very helpful to get ideas when trying to troubleshoot.
