Take it off the car and check it. You'll get nothing. Whatever it is is coming from somewhere else. Thermistors (or any other resistor) don't generate voltage.

The Yellow/Red is for the oil pressure sensor. Your probably going to right away say *nah, I already have a wire on the sensor and it's something else*. Not really. The yellow/red wire has another wire spliced to it. It's yellow/red also and terminates in a single black connector. THATconnector goes to a thing called a condenser or capacitor which attaches to the bellhousing/clutch slave cylinder (somewhere in that area).
It's likely that part is missing in action. IF the engine has ever been taken out there a good chance it got tossed.
It's meant to aid the oil pressure gauge/sender. To protect their circuit, I think. The gauge will work without that condenser. That does not mean you should delibertly run without one if you have it to install.

And Karack, a man of your upstanding position in this forum, please tell me your not a tight-wad when it comes to your car, cause your to close to where I live for me to have to come and replace all of your electronics with 'NEW' ones! Your a good man,

well i haven't replaced sensors because of age no but i did test them when i rebuilt the motor over a year ago and i will again when i install the standalone this month, you are more than welcome to replace all my sensors if you want though.

lol
MINT87RX7, most oscilloscopes were made before most of us were born, sometimes i must question the condition and readings the units give out. we usually toss them in the dumpster at the dealers because we have digital oscilloscopes now which are less likely to give false readings and are self adjusting to inputs.

Karack, was that a response of good nature or snottiness? My point, if I need to rephrase, is to buy a new part that might assist in the early warning system of the rotary engine and its corresponding computer accessories to avoid a problem in the next 10 minutes that is telling the person behind the steering wheel that this is about to BLOW. I get window regulator spools, ash tray springs, interior molding, heater vent lenses, intermittent wiper, cruise control, hazard switches from the junkyard, not early warning sensors telling me to shut it down, or pay for a new engine. How is that for simple English? And I was referring to original post, and paying you a compliment, or was!

First, turn the car off.
Then, remove the connector to the ECU.
Now, connect each lead of the ohmmeter to each terminal on the sensor.
Look at the screen, note the resistance.
Get a temperature reading of the water using a thermometer.
Compare the resistance you see to the specs in the FSM for that temperature range.
Sounds like those "electronic techs" should go back to school.

This thread is dead but it is really bugging me. An O-scope reading would prob be analog not digital. If you have a square wave at some binary value then that would be digital.
