I am going to put an oil pressure Gage on my 22re, but I have a question....
in the book it shows 2 sensors, one is the oil pressure switch and the oil pressure sensor. it says to put a Gage on the oil pressure switch hole, beside the oil filter.

whats the other one for, its listed as the oil pressure sender, on the lower front left side of the engine?

why does it have 2 oil sensors?

There is only one sender. Is either a switch for the base model or the pressure sender for models with the oil pressure gauge.
The manual is confussing. If you look closely at the picture, there is an arrow that points from the pressure sender to the switch. It means the engine uses one or the other.

I see... thanks!

Yup. Switch for the 22R idiot light (like I have, appropriately ), sensor for the RE or RET ECU and/or the SR5 guage set which has a guage in it.
And now I'm totally initialed out.

Allyia

they all have the same thread size right? the line and gagei picked up I matched to the gauge sender, not the light sender (I had advance auto show me the gauge sender so I could make sure the threads were the same.)
I HOPE they are both the same threaded hole!

That I have no clue on. Mine keep on working, so I've had no reason to find out. I'm sure someone knows though...

Allyia

same thread, it went together fine.
dont start the engine with the sensor out... it makes a mess.

there is two sensors, one below the oil filter and one beside it and both are hooked up... I used the one below the filter as it what I recognize as a light sensor switch. I dont know what the other one is.
the light sensor hole now has an oil line into it.
which leads to a curious question....

whats the 22re's normal oil pressure suppose to be?

mine once it warmes up idles at 65-70 PSI. I think the gage might be bad but I checked it in the car I removed it from (I put it in that car, it always worked fine) before I took it out.
do the 22's run at this high a pressure?
I will take it for a spin tomorrow, the gage only goes to 100, so I might be in for trouble.
I might pick up a new gage to be safe.

Another hint: Don't start it with the valve cover off, either, unless you feel like having a neat-o oil spray pattern on the walls and ceiling of the garage.
We had a "professional" mechanic out at work who claimed to be a total expert on all things Toyota, and most every thing else in the world, come to think of it. He also turned out to be both a certifiable megalomaniac and pathological liar. Hmmmm....Anyway, he had his 86 p/u in the shop to do something under the valve cover, and as a demo to someone, he fired it up. Oil everywhere! Walls, floor, ceiling, the truck, the bystanders, all the equipment in the shop...And I guess what teed him off the most, other than having to clean it up himself, was everyone laughing uncontrollably at him. He was the "Lead Mechanic", and used to having people (not me, I was lead on the Electronic's side of the house) do everything for him, so having to clean all that oil up really griped him. And, being a megalomaniac, having a roomfull of people laughing at him was just maddening! Awwww, poor boo-boo...
As far as I know, the correct oil pressure is listed as > 4.3 PSIG @ idle, 36-71 PSIG @ 3000RPM, IAW FSM. Any more than that, and the bypass valve in the pump may either be clogged or purposefully misadjusted in the misguided search for higher than factory oil pressure.
The heavier the oil, the higher the pressure, the warmer the oil, the lower the pressure. The indicated pressure will be a vector sum of those two factors.

Hope that helps...
