2014 sonic 1.8L engine has multiple coolant temp sensors. One is on lower side of radiator. Where are the other engine coolant sensors?

I only see one.

Where is your information coming from?

It looks like there is one on the thermostat housing and there is another sensor near thermostat housing on the engine block? I am hoping someone can clarify what these two are if not temp sensors

There are two.

I wonder if they're the same part . . . and that'* why I'm seeing only one part for this car.

I what look like 3 sensors. One at bottom of radiator, one on thermostat housing and one next to the thermostat housing on the block..so I am not sure if all 3 are temp senors

Click in Charm and find all the info.

It looks like the resistor (on the radiator fan itself) for low speed fan was not working. I replaced the fan assembly with the resistor. Now, my a/c cycles on and off every 10 sec. Before I replaced the fan it would go on for much longer..although the fan a believe was only running at high speed before. Now I believe, it may be running at lower speed initially when a/c is on. Chat GPT says 10 sec is too short and indicated a problem with system

Ten seconds does seem short, but it depends on how much cooling has been demanded. Does it still do 10-second cycles if you have it on max and full cold and full blower with all of the doors open?

I can't believe it. I ran the A/c at all the way cold with fan at 3/4 speed and I watched the a/c compressor run for 2 minutes straight without cycling off !!!
