Unknown sensor

I have a 87 TC auto with climate control and have a sensor that is a in-line sensor in the metal coolant line that goes to the heater core and the wire harness that hooks to it goes through the firewall inside the car, like where the heater core is....what is this sensor, it's not the coolant temp. sensor like I thought and the parts houses can't figure it out.

Its for the EATC system... As long as your heat works, don't worry about it...

Would that be the "electronic automatic temp. control?

Thanks for the info.

I broke mine when I did the heater core two weeks ago. No issues and no codes.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

Yep. It tells the system when the coolant is hot. That way when you turn the heat on and the coolant is cold the system doesn't blow cold air at you. It waits till the coolant is hot before air comes out.

Right!
It keeps the outside air/ recirculate door in the recirculate position and keeps the blower off until warm.

I wish the ECC in my 95 worked like the 88's does. In the winter the 95 blows cold air the minute you turn it on. The 88 sits in the garage all winter so I can't use the ECC in the heat setting :hick:
