Coolant Temperature sensor sending unit

On a 1993 22RE, where is the coolant temperature sensor?? After reading Haynes, FSM, and online searches, I can't find it.

Keywords: CTS, ECT sensor, Coolant Temperature Sensor

EDIT:

After much soul searching, it appears that the Engine Coolant Temperature (ECT) Sensor is attached to the green connector below.

THANKS, DubVipers (I swear I did multiple searches)


Does anyone know how to test this according to the FSM, which specifies decreasing resistance as temperature increases? Specifically, how do you measure the temperature? (No #'s on my dash temp gauge) Or do you just start the vehicle and watch the resistance dec. as it warms up?

its the green one, take it out and stick it in cold water and measure with a volt meter on ohms setting., should read high ohms in cold and low ohms in hot water. low being 0.2 high being 1400. hope this helps.

Thanks, that helps.

It would be easier to take it out and test it, duh. I thought I had to test the unit by running the engine and measuring the heat in the radiator...

Keep in mind that the discussed sensor is the one that reports to the computer, not the gauge.
