I think my TPS may be bad, so I am wondering which TPS's are interchangable if any or if there are any other Throttle Bodies that are interchangable here stateside.

well... my TPS is reading higher voltage than spec, and varying at times, sometime normal sometimes high. Stock spec should be about 0.6v closed, 4.0v WOT. I am getting 5.11v from half throttle to WOT. I adjusted the TPS as far as it would go and still getting 5.11v.

S-AFC shows I am at about 10-15% throttle when the throttle is closed and shows 100% throttle from halfway thru WOT.

Well I have been having a problem prior to installing the AFC. I installed the AFC so that I could monitor issues as such. I am going to test the sensor with a voltmeter tomorrow like the FSM says to see if the TPS is in fact bad or not.

have you tried recalibrating the TPS sensor?

Yes I have tried recalibrating, and the funny thing is the voltages vary. May be a wiring issue.
