2001 Silverado DBW to Cable Throttle Body Conversion Hi,
I am having a hell of a time trying to find a replacement throttle body for my Dad's 2001 Silverado LS 4.8. Was hoping to get this done before he's out of the hospital but no joy.
Seems like every single auto parts distributor has these drive by throttle bodies as NLA.
We replaced the TPS sensor given the codes we received, but this did not fix it after the OBDII reset.
The codes are still:
P1120
P1220
P1514
P1516
Whenever we reset the OBDII codes, the truck runs like nothing is wrong. After turning it off, and restarting after 5 minutes, the SES light, reduced power, and all codes return.
So now what? Do I convert to cable if replacement TBs went the way of the Dodo? If so, what is needed? I assume the PCM is going to error out given a missing signal for actuation of the TB. Does it need to be tuned out?
Thanks in advance for reading. He just wants it fixed so he can get back to work after recovery.
