hi LT1 buddies,
I have a 1996 Z28 5.7 manual 93k miles and I had a few electrical problems that i solved and cleared the PCM memory of using a Code scan/reader device i ordered of eBay called memoscan (neat thing, OBD-II). all 12 codes or so were cleared and i had already changed the components like tps iac maf, etc.. i cleared memory and only one code remains, I am getting, p1641 MIL Control Circuit, not really sure what that is all about. but im guessing the actual SES circuit is faulty? im just trying to clear the MIL light with repairs, im sick of having to take the bulb out of the dash like all other cars i had (LOL), i spent big $ on electrical components, just this one code remains, help apreciated.

RE: (MIL) Service Engine Soon Code p1641, pls help
This forum can be a little slow, especially right now, so be patient for an answer. Also most people don't post if they don't know the answer, so look at the bright side, at least people aren't feeding you BS
That being said, I haven't seen that code specifically before. It seems pretty specific though, something is wrong with the circuit that tells your SES light to turn on or not. I don't know any common causes for it though. Wait around a little more and maybe someone can chime in.
