I was under the hood of the wife's truck and was looking at the extra gizmo on the injector-pump that the 5-speed trucks don't have.

I hadn't noticed before, but there is a place, on this gizmo, for wires to be plugged in; the trouble is, there are no wires plugged into it.

I sort of looked around and could see nothing extra hanging around that looked like it goes there.

I assume this has been like that since we bought the truck.

It shifts fine, drives good, and gets excellent mileage.

Should something be plugged in this device; and, what are we missing from the lack of it??

Thanks.

 

All I know is that it's the throttle position sensor and that it has something to do with the tranny grabbing overdrive. Beyond that, I haven't a clue, but here's your bump to the top!

 

where about's is this "gizzmo" located on the pump? top front, lower outboard, bottom back???? the one on the top is the throttle position sensor, the one on the side lower outboard on mine is unplugged also and the truck runs just fine and not really sure what it does (forgot to research it when i went in for another beer) and the one on the back is the fuel cut off solinoid.

 

Right on top and right up front.

I think it is the TPS.

Thanks.
