HomemadeTurbo - DIY Turbo Forum - Codes 10 and 14 NEED HELP, ASAP!!!

FIXED!!!... well sort of
Okay, the plug on my purge valve went on my IACV, but since I only had codes 10 and 14, I never touched it.
My IAT was melted and even though if never gave me any trouble in the z6, I guess it was the end of the road for it. Oh how i'll miss it... R.I.P. IAT sensor :X 1995-2006
I swapped the IAT with one from a 94 Ls IM I had in my garage and that did the trick.
I unplugged my purge valve and it didn't throw any codes so I'll just take it complety off tomorrow.

There is, however, a small problem:
I have this engine in a 90 hatch that is converted to obd1 so I grounded the ecu wire with a toggle switch inbetween to make my CEL flash me any and every code.
If i don't touch it, its fine and I have no CEL on but if I switch it, it gives me code 10 again.
So I took the ecu fuse out for about 10 minutes (dranked a few beers and called my ex), after burping a few times and deleting all of my ex's pictures from my phone (well most of them anyways) i put the fuse back in and the same thing happens.

Why do i only get the code if i flip the switch?
