02 superduty no throttle response
 

New to the site an need some help.I have a 02 superduty 7.3 241,000 miles
about 2 yrs ago I had the same issue with that being said it starts up the check engine light comes on but no throttle response I replaced the pedal assembly 2 yrs ago an now Iam having the same issue.
I’ve read that it could be the od wiring in the column but all my gauges are on an when you push the od button it lights up,I haven’t blew a fuse so I don’t think that’s the issue.
I replaced the tps an still no throttle.
Iam leaning towards replacing the pedal assembly again but don’t wanna just throw money at it an not fix the issue.
