Trottle position sensor
Can anyone explain to me what the throttle position sensor is, what it does, how it works, and what happens to mileage/performance if the two wires are disconnected? I've got a 85 BII with a 2.8 engine, Motorcraft 2 bbl. carb Thanks in advance.

It should run like a sick dog with it pulled. It controles your air & fuel input to the computer that adjusts everthing for the best running & least polution. I have one on my 89 Bronco II , that is fuel injected. How does it run? With it removed it should run in the limp mode (make it home barely).

tps are used on efi engines and if you have one on yours, and you say you have a carb pls send photo to show. your best bet is to invest about $9. in a good repair manual , HAYNES or CHILTON you can get these at your local parts store. they have photos and good directions on how to about anything you can do at home, repairwise. rc.

Yep, the 84-85 BII had computer controlled feedback carbs, and a TPS. They tend to be hard to get to run correctly (at least my 84 was). I finally changed to an early model carb and a Mallory distributor.

The TPS is located on the end of the throttle body shaft. It serves the same purpose as acceleration jets on a carb. If the throttle is opened rapidly the TPS senses the rate and tells the computer to momentarily richen the mixture (increase injector time) to accommodate the sudden increase of airflow.

To answer the question you had, your tps is behind the choke. It's alittle bit of a pain. As far as the individual that said carbs don't have a tps obviously he doesnt own a vehicle with a feedback carb. I just replaced mine about 6 months ago. Good luck. If you need anymore help on this matter you can e mail me.
