po 716 code on my gtp

[SteveCZ28]

po 716 code in my 97 gtp came up yesterday....it is input turbine sensor parameters out of range...i dont know exactly what is causing this, or where to even begin. but for what ive read on the subject it causes the transmission to either not shift, or not shift properly/ thru all the gears. now heres what confuses me...my car acts like nothing is wrong, it shifts perfect like it has the whole time ive owned it. goes thru all gears, doesnt slam, slip or skip gears. tq convertor still locks up the way it should. so i dont know where to start or what to even do...ive seen some similar problems like mine that resulted in the tranny being removed torn down to replace a "reluctor wheel"? ive never torn into a a/t tranny before, and dont want to tear into it and mess it up, or find out i didnt need to tear into it....any help would be greatly appreciated here. thanks in advance guys

Sorry I missed this man..

Here check this out if you have'nt already.

Though I am not sure if the 03's were still using the 4t65e or not.

So here are the rpo's. 4T65-E, 4T40-E or 4T45-E Transaxle (RPOs MN3, MN7, M15, M76, MN4, MN5)

Everything I have researched suggests it's bad wiring to the sensor plug or the sensor itself.

Pull the side cover and ohm the wiring. The trans adaptation maxed code will probobly be thrown next from what you're saying.
An 03 is the same but not. Harness is a bit different but ohm specs etc should be the same.
