Hey Everyone,
My favorite truck is driving me nuts. I've had an issue with the throttle pedal going dead. I replaced the entire pedal assembly with the new IVS and TPS about a month ago. Everything was running great.
I'm not sure it's related at all, but I then had someone try to steal my truck by drilling out the ignition switch. They drilled a bit too far, but when I put a replacement ignition switch in, everything started and worked fine (with the exception of I'm getting a B1352 code). I drove the truck several times and everything was great.
Then while driving the throttle just quit responding completely and the SES came on. Limped it home and connected Forscan which shows a P0122 code.
Troubleshooting I've done so far:
What am I missing for troubleshooting steps?
Thanks in advance for any help!

Troubleshooting I've done so far:
- Tested all fuses, all are good.
- So while the truck was running I looked at the IVS while hitting the pedal and it is showing "off throttle" correctly.
- With key on, engine off I tested the yellow wire at the TPS plug. I have a good ground.
- With key on, engine off I tested the brown wire at the TPS plug. I have a solid 5v.
- With key on, engine off, I probed the grey wire at the TPS plug and depressed the pedal to see if the voltage changed. The voltage went from ~1v - 3.6v.
What am I missing for troubleshooting steps?
Thanks in advance for any help!
