Mechanic cleaned my TB's throttle body and then charged me an additional $50 to re-program the computer, claiming it was necessary. Is this really required or complete BS? Thanks!

Smells funny to me... Did you ask him why...or why he didn't check
with you before incurring the additional cost?

Generally speaking, except on April 1, it's not necessary to reprogram
the PCM for a throttle body clean, just clear the parameters it has
learned while running with a dirty tb. That's all we're doing when we
disconnect the battery during the clean.

Cheeers-

Ha, forgot it was April Fool's! Unfortunately, I don't think the mechanic was joking about the $50... Thanks for the info, I will see if I can dispute the charge.

I agree with everyone else. All I've done or ever heard of being done was to disconnect the battery for at least 30 mins or the time it takes to takeoff the throttle body and clean it. Was this a Dealership or just a local mechanic?

Before you get too pis**d at the mechanic, he may have done you a favour.

If it was a GM tech.

Your truck is an 02, a number of program updates have been done to the PCM over the years. $50 for the updates is a good deal :yes:
