WTF, my Gryphon reads 0 EOT all the time. Didn't think it had a sensor. Don't tell me my programmer/tunes are buggered...........

 

Do you have a 4.6 by chance?


And thanks Jack, that makes sense. But is it a bit early to have to need to change it? I mean the truck on has 68k...

 

I have 5.4L FX4.

 

No idea then... the 4.6L's didn't have a a sensor from what I read. Got nothing, sorry man

 

Some people change the stat every time they do a coolant flush on general principle.

 

Alright, going to have to look into doing this soon, thanks everyone

 

I think Ford stopped installing an Engine Oil Temperature sensor in 2007 on all engines. If you have a truck from that model year or later, there's no way to read EOT. It's not the programmer's fault. And, without the sensor, the EOT reads 0.

John, the stat really explains all the symptoms. I agree, it seems too early for a failure, but, "stuff" happens. (I'm just glad glc was bright enough to see this, since I wasn't.) :o

Well, this thread has been thoroughly hijacked - so, this post is directed to the original poster.

It's recommended that you raise the warning threshold for the EOT to 250 degrees.

 

Yeah sorry about that OP

 

Since the 250 threshold was advised at the beginning, I wasn't too worried about the hijack. And, both had what seemed to be "cool" running trucks, which is not a good thing.

Nothing to be sorry about, in my opinion, but thanks, glc, for refocusing the subject.

It's Ok guys. I didn't mind the additional info being tossed my way. I'm going to raise my EOT. But why would Ford or PHP set the EOT default alarm at 200 vs 250. Where It should be.

 

Bump

 

Ford didn't - this was some brilliant idea on the part of Edge. The truck has no "alarm" capability at all, for oil temp. And, I've got two Edge-produced programmers, the old monochrome one and the new CTS kind. Neither of them came to me with the EOT alarm set that low, so it must be something they've recently done.

It's an interesting question though. Ford and other makes actively monitor oil pressure. (In Ford's case it's really just a simple pressure switch that says things are fine if the pressure is above a certain threshold, if you have a gauge, it just makes you feel good.) But - the PCM will force the engine into failsafe mode if the Cylinder Head Temp goes above 258 and will shut the engine down if the temp goes above 310.

It would seem to me that it would be easy to program the PCM to do something similar for oil pressure failure. (Shut the engine down after a brief warning time, maybe 1-2 minutes, to avoid engine damage.) That way you'd have time to pull out of traffic safely.

Jack, do you have a list of the alarm settings that is recommended? i would like to go through and adjust all alarms to general safe operating limits.

thx
