Serial# AF17D04222 Shows Code E-23(Throttle Position Sensor signal Malfuntion) This truck had the same code about 6 months ago and changed out the Electronic throttle assembly and it cured the problem,now the code is back,have a hard time believing the throttle assembly went bad already,according to my troubleshooting info it tells me it could also be the relays are weak/bad,do know this truck is in a very severe dusty enviroment in a feed mill and have found connectors plugged up with feed dust before at this place. Was curious as to what others have found with this code besides broke wires at the connectors and such?
I'm thinking possible the relay or relay box connections are getting corroded and causing the issue but wont fing out till the moring when i get to the truck to look at it,just wanted to put some feelers out on here to see what else to possibly look for.
