Oil Summary Page on Instrument Cluster

[Bad Daddy]

In the Oil Summary page on a limited, it has three “gauges”.

Oil life, oil temp and oil pressure.

The oils pressure is just digital, and other two are digital and analogue gauge style…

Is there a way to get the oil temp to show as a dial?
So all three show the same way?

It does show it correctly in the off road or trailer tow pages on the 12” screen.

Strange!

What engine do you have?

Previous posts tell me he has a Cummins.

The Cummins doesn’t have an oil temp sensor, it’s just a calculated value. So it may or may not be correct at any given moment. An analog gauge wouldn’t be very useful.

Doesn’t have an oil pressure sensor either. Both oil temp and pressure are fake, may as well forget they exist.

This first pic is what I expected.

The second pic is what my instrument panel is showing when on the same page.

I’d like it to show as the first example.

Digital readouts aren’t my friend.

The first one is a gas engine, yours appears to be diesel. That could be the difference since those gauges are real on a hemi and fake on the Cummins.

 

[Bad Daddy]

So there’s no oil pressure sender on a Cummins?

Odd that the gauges in the off road pages show the temp ring, but not instrument panel…

Mine does the same thing! I was just commenting about this to my wife.

I believe it displayed properly when I first got the truck, then went intermittent, and now never shows. I wondered about disconnecting the battery, or a reset at the dealer, but honestly I probably won't do a thing about it except complain in my little brain from time to time (unless you or someone figures out a fix).

Do you know if anyone has tested the oil temp, and oil pressure to see how close the calculated display is to the real temp and pressure?

The isn't an oil pressure sensor or oil temperature sensor. There is an oil psi switch, so as long as you have 6 psi of pressure (10 psi is the minimum at idle per Cummins) our gauge will read "normal".

I ran real oil psi and oil temp gauges in my 05. The oil pressure is rarely correct, the real oil pressure swings much more rapidly and sits lower at idle-1500 rpms.

Oil temp is decent, close enough that I thought I was a real reading when my dad bought his 2017 and I still had my 2005. It's a little funky when cold, like it will drop from 190 to 160 on an off ramp, which isn't realistic. It also doesn't get quite as warm on a long hard pull, but it's generally closer than oil pressure.

But that's all just for fun, neither one, especially oil temp, will ever let you know if there is an issue.

^ same oil psi performance that I saw on my 04.5. I remember being quite surprised.

 

[Bad Daddy]

I think the the digital instrument panel should have the oil temp gauge with a blue ring like all the other gauges. I want consistency, dammit!

I did a post in another section about this . I had the same problem but also the center stack did it too. They change out the center first time and it fix it there but not the dash. Every now and then when you check the dial will be there then it is gone. They have put 3 dashes into my truck still is wrong. Now they are gonna call in somebody higher up to look at it. It just never will show the blue ring.

 

[Bad Daddy]

Center stack on 12” works as it should.

The instrument panel does not.

It’s got to be a programming thing because it works on the gas models. Just not diesel.

I tried a new one at the dealership, and same issue.
Center stack works, but not instrument panel.

 

[Sabre king]

My center stack was pretty bad , it didn't show a lot of them properly. The phone was the big one it would pick and drop the Bluetooth constantly. even when the mechanic tried his phone it would just drop it. now they are waiting to get somebody higher up to look at the dash to figure it out.

 

[Bad Daddy]

What if you switch to off road page? Same thing?

Every thing else is fine, just that one gauge, that of course is dead center, lol.

Driving up the Coquihalla towing a loaded flat deck or boat, it’s good to have a “gauge” and not a numerical read out.

I know it’s not a real gauge. I know that the Cummins doesn’t have and oil temp gauge.

Whatever. I just want consistency!

 

[Sabre king]

The big problem is we checked other trucks and they had the gauge working with the dial and the blue ring. I can change all 5 tiles to the same gauge and they show the same, nothing . Even when you scroll the pages to that page it will show nothing. Sorry one day it will have the ring around it another it will just show the number. I am on my 4th dash now with the same problem. The center was fixed with the one switch, it was mostly the Bluetooth was messed up. The off-road pages did work right with all the gauges . Its one hell of and expensive truck to not have it right.

 

[Bad Daddy]

The other thing is the gauges should be consistent in linear reading.

If you look at what 198°F is on dashboard, to what it shows on center stack , digitally they are the same, but the ring is further along on one and not the other.

It’s like having a tape measure that has inconsistent markings.

Some good engineering and approving there.

Curious about this, have seen your posts on multiple sites stating the oil pressure sensor is fake…are you sure about this on the newer 6.7s?

While the display may be fake or altered for whatever reason, the sensor being a 6 or 7 psi switch does not fly. This is a single wire switch (has two wires in connector, but only one used) that is normally grounded to block. If you check resistance static it is about .5 ohms & increases with pressure applied.

I can state with certainty it is not simply an on/off switch. Mine failed & I installed a 10psi switch, no joy.

Cummins even calls it a switch, not a sensor. The part crosses all the way back to 2007.



Not sure if it changed for 2025 or not.
