Hello again everyone. I had previously posted about a 2/3 shift issue i was having with my 42re. However, upon a heck of a lot of research and diagnosing, I have come to suspect that the shift issue is a direct symptom of the P0123 ( TPS circuit A high output) code that does not seem to want to go away. I have tried a new TPS, still nothing. I have traced wires, cleaned grounds, cleared codes, jumped rope, rubbed my tummy... all to no avail. My TPS signal output is at over 5v with KOEO, no matter what position the TPS is at, or whether the pigtail is plugged in or not. So, basically, the signal wire is being fed over 5v from somewhere, back to the tps itself. I assume this wire should be dead when disconnected from the tps and should only be supplying power back to the PCM through the TPS itself??? The 5v supply is reading 5.63v while the signal wire reads 5.11v. so i dont think its the TPS supply crossing over. I've got the CS and speed controls disconnected at the column all the while. Was hoping anyone here could chime in if they have experienced this before. Maybe point me towards something i have overlooked. I may just pull the entire harness and check wall the wires one by one, but im not crazy about that idea. Thanks ahead of time for any and all help, or even just reading through this.
