Here is a code stumper! P1543

And I checked all the usual code lists online...nothing!

I can't find any info on this thing.

Any code savvy people know what to do about a P1543 or can at least point me in the right direction?

thanks!

Really?

I google searched it and came to this site http://www.findonefindall.com/obdii-errorcodes.htm

Is that where you found this info?... I thought that was the answer too, but if you look closer you will see that it is under the AUDI DTC heading and not under C5 Corvette.

Yea...it's the darndest thing! If you look in the manual for P1545, I believe, you will see that it says something to the effect of...confirm and run checks for P1543, but then you go to turn the page back and find it and it only shows P1539. It goes from P1539 and then jumps to P1545. It mentions P1543 in the text for P1545, but there is nothing on P1543 any where

That is just freakin' odd!

At least you know your engine is not in imminent danger of blowing up.

Thanks guys...I had a feeling it was AC related since it fell between P1539 and P1545.

Good link there Mr. Lucky! It lists all the codes in between. The manual doesn't even do that!
