Tps voltage

Hey guys. I put our scan tool on my 97 2.5l the other day and pulled the voltage on the tps. At closed throttle I was getting .6v and at wot I was getting 3.8v. I've been dealing with an occasional rough idle and was wondering if this has something to do with it. I cleaned the IAC today and it didn't help. I have been getting a trouble code from the ECM of a power steering switch. Any help would be appreciated as we are heading up to Beasley Knob on the 3rd and I would like to get it squared away by then. Thanks

Did you get 5v supply to the sensor? The idle voltage looks low which would cause a bad idle if it is. Jeeps are a funny animal, but idle is usualy over 1v and wot is anywhere up to 5v because the voltage going to the tps from the computer is 5v. I don't know if there is an adjustment for the tps on Jeeps.
