your own post:Please provide a reference for the claim that the PCM can read anything like a high pressure and throw the gauge to the max. I don't see support for that in any manual I have read.
Huh? Where did you get that from? Not only do I not see that in Roadie's statement, but we have NEVER seen that happen here.
Maybe you could highlight the part you are referring to. I guess I'm blind.On the V8, the oil pressure sensor is a true analog (continuous) sensor that doesn't lie. On the I6, I only see it as a on/off switch (can't find any evidence it's a 3-way in 2004). Other years may be different.
So the normal idle pressure display is 40 PSI, and when you rev it up the PCM adds a little bit to the display because it helps "fool" people into thinking they have a real gauge. People's mental model of an oil gauge is that it moves a bit with RPM, so the PCM programming was fiddled with to match that mental model and enhance the charade to keep Ma and Pa Kettle happy with their technologically advanced vehicle that they understand only 5% of. :weird:
For the Kettles, their trailvoy IS the Matrix. Only we on trailvoy know the truth. :thumbsup:

Just to review, the CHECK GAUGES light will light and very quickly go out. The gauges look fine. A few days later, the light comes on again. It took 2 or 3 times before I caught the oil gauge on 0. As the light went out, the gauge climbs back to normal.
True, but your phrase ". . . instantly throw the gauge to the extreme . . . " is what confused us (maybe I should say me).I just reread roadie's post, I didn't specifically mean high pressure, there are two extremes to a gauge you know.
