Hey folks...was driving and the SES light came on. pulled into a Auto zone and ask the man behind the counter if he could pull a code for me. he did...it was Code 21.....looked in my Service manual...I guess I need help deciphering the lingo and what do I do next....any suggestions?
Johnny sorry I can't be more specific as I have not worked on that system. I found a thread in the arcives that may help. You might be able to clean it. The alignment after install looks to be the hardest part. Maybe someone with more knowledge will jump in.
If it is infact the TPS sensor, maybe you should check the output voltage. I think the correct value is .54 V. This would be on the top two pins I believe. There is a thread here about setting it. But if you check if you should know where to go from there.

Did you try to do a search on Throttle position sensor???
not yet...just taking baby steps with it. I did do a search and one site mentioned disconnecting the battery for a few moments to see if the ECM resets. I don't know a whole lot about this voltage issue or where to begin. I am afraid that I need things broken down "Barney style". Maybe I should try to find "Corvette's for Dummies" at my favorite bookstore. Seriously though, don't have a clue on electrical stuff or how to check the voltage.
