I see that on this wiring diagram it’s marked 1Mz-fe which is 3.0L engine. Engine Im working with is 2.2L 5S-FE. Don’t know if it would make difference in wiring diagram.

There’s no sensor there and there’s no wiring that would be there for the sensor. All the coolant sensors are next to each other by the throttle body on the thermostat housing/water neck.

How would I go about checking this single wire sensor with multimeter?

Thanks, I’ll look for one that has one wire. I thought it was for just the gauge on the dash, not the actual ECT sensor that controls fans/connected to pcm?

There is NO sensor on bottom of radiator. Maybe this car has aftermarket radiator but there is NO sensor on bottom of radiator. There are 2 drain plugs and atf cooler lines that run into radiator.
All the coolant sensors I see are on thermostat housing next to throttle body.
I’ve checked this sensor and it works as it should

I even had a spare on laying around and I’ve installed it and it hasn’t changed nothing.

A/C is not on, even though A/C fan is going as well (one on passenger side)
Gauge does show normal reading, right in the middle, coolant is good and full.
Both fans are on as soon as key is turned to ON position and they keep working as the car is driven. They are pretty loud so I know when my aunt is coming as I can hear those fans spinning half a block away lol.
I did replace both of the fans as they were blown and car was overheating in the summer. I do remember that fans would constantly run before they both blew.
