line coming from throttle body.

[john110]

i can see that is a 91+ Throttle body
but look at where the wire goes,it's not to the body. not really.... (not injector, not tps, not iSC) there are no more wires to TB but... but the base can have this PTC device.
its a separate base plate, I cant see where your wire lands.

see TB removed (1989/90 ) A/T only
the base heater plate is here, is this it?



look more careful, i bet grease hides the color , its brown plastic.

Fix , I think it`s call 'thermoprobe' which is on the 94-95 Tracker and sidekick as well as the California additions. It would not have this on a 92, unless the car is set up for California emissions.
It registers the temp of the exhaust gas that is going through the EGR valve.

I have the same thing on my 94 autom Tracker.
