Exactly same thing as this post. But every thing he said to check is good. Truck already has 2 new TPS sensors, and 2 New/reman PCM's, plus the original PCM. Still P0123

Customer: TPS sensor. DTC P0123
JA: What is the model/year of your Dodge?
Customer: 1998 Dodge Ram 1500
, with a 5.9L V8 gas engine. Auto trans 4 spd, 4x4, a/c, cruise control
JA: Are you fixing your Ram 1500 yourself? What have you tried so far?

JA: Anything else you want the mechanic to know before I connect you?
Customer: I have 5.10 volts on the tps signal wire going into the pcm. The pcm is putting OUT 5.10 volts, on what should be an INPUT signal from the TPS. disconnected every fuse and relay in the PDC, brake
