That is the Rack Position Sensor. the box on the back side of the IP.

It sends a signal to the EGR Black Box behind the Passenger kick panel.

It is all part of the smog emissions on the 85. I thought the 84 had it also, maybe late 84`s had it.


In your other thread you asked about the FW sensor which sends a signal to the black box. this is just another part of the puzzle.

I would say it can be ignored with out any problems, unless you are going to keep the EGR and all the emissions stuff hooked up.

I do know the 85 pump with the RPS can be used in another vehicle w/o the black box. the pumps work the same. the FSM explains it pretty good how it works as I remember.
