87 2.5 TAC Sensor

[streetjeep2.5]

With the fact that my engine leaned out and it got "hurt", and it may have been due to a vacuum problem, I am replacing as many vacuum sensors and all the flexible lines I can prior to putting the engine back in and firing it up. There is one in the cover on top of the throttle body. My Chilton calls it in the Vacuum Diagram a TAC sensor, but that is the only reference I find. It has two lines to it which I take to mean vacuum flows through it, and it then sticks through the cover into the air as it comes into the throttle body from the air cleaner. Throttle Air Control????? They don't discuss it anywhere. Anyone know its function and if it might be available anywhere? Local dealer can't find it in the books, and local aftermarket fails also.

I could use this information too.... :help:

It's a temperature sensor that controls the warm air inlet in the air cleaner box. When it's cold it pulls warm air off the exhaust manifold.

And as far as I can find, they are not available anywhere.

Its that about 1 inch in diameter round sensor with two vacuum connections in the round cover that snaps on the top of the throttle body of the Renix 2.5, at least in 1987. Sorry, no pics. And, by none available, I meant new.
