is reset and reprogramming Throttle Body mean the same thing?

Its a good idea to battery pull to reset the codes when you reset your TB becuse what ever caused it is still active, I got limp home mode from a random misfire and the code was still active and kept tripping the limp home until i battery pulled.
-
So far, so good. After months of fighting with the codes over and over, this may be the cure I needed. Thanks!

I have tried to do as your video says but for some reason that cog or whatever does not move. Any suggestions what else, because I am going to try to clean it.
-
Thanks, that's what I needed !
A clean up will be nessessary off case which usually is the root corse.

@JustinHiFi agreed. my limp home kicked in because of a known vacuum leak i had. i kept driving on it and made it kick in, so i had to all this to reset the limp home mode. so far so good.

@artstran If it goes back into LHM every time, must replace the throttlebody assembly. Internal failure.
Difficult to say exactly without the vehicle in front of me, but if your having surging at idle, it can be from a bad TB, or possibly vacuum leaks.

I have a T5...Is there a similar procedure?

@piffdaddy420 T-5 does not have an electronic throttlebody. If you have TPS codes, the sensor is on the side of the TB. Just a simple swap.

Sorry for the delay in reply, I did not get an email update. Usually a thin spray based lubricant. I usually use a dry lube spray. Im sure many other types would work just fine as well.
