P0123 TPS code.....?
I have a 1997 12v with 104k on it. Trans was rebuilt at 100k.
A little while ago I lost overdrive.
Just got my hands on a scanner and it pulled code P0123, and says "TPS Circuit 'A' high voltage input."
Any ideas?
I have to drive about 100 miles tomorrow and I dont enjoy hearing my engine screaming at 2300rpm while watching my speedometer stuck at 55.

the only thing I could think to check would be ALL the connections under the truck at the transmission, mine did a similar thing yesterday and it ended up being one of the wires in the PRNDL switch near thepan rail. Sorry I couldn't be much help though. Good luck
