Hey I tried to contact you directly, but I couldn’t figure out how. So what happened when I moved the butterfly will full power going to the engine (not started). Please give me a little lead way this was a year and a half ago before I knew much about cars. But now it is throwing high voltage codes about the throttle body and gas pedal. It won’t let the computer relearn it and I’ve replaced the throttle body and accelerator with no avail. Is there something I could have shorted in the harness or bcm? I’ve replaced the ecm and tcm still the same codes

 

What are the codes?
What you might have done is break the motor that turns the butterfly.

 

Well that’s just it we just dropped a new crate engine in and it had a new throttle body already installed. It has a new accelerator pedal as well and when we try to relearn it says “throttle body system failed relearn failed” let me go check the codes. At this point I think it I’ve shorted the wiring or something

Direct thank you!

 

What are you doing to make it relearn? All it takes is idling for 30 seconds.

 

Using a scan tool to relearn

 

Guessing that the code is P0223.P0120,P0122,P0123,P0220,P0222,P2135 here is the diagnostic tree.

 

Somebody recently said that the TB connector and the injector connector could be switched. He did that and ended up with a fried ECM.

 

Just to be clear. Is this a SS ? Is the crate engine a LNF engine with the stock throttle body ?
