dude, use commas and periods please. It took 5 minutes to figure out what you were saying. And im assuming you mean egr.
Okay, what im getting is that you swapped in a non egr engine into your 1994 celica st and now its throwning a code. right? If so you could possible get a jdm celica ecu, but that depends on what engine you have in there. as far as installing your old egr setup, its really important to know what engine your threw in there and i imagine it would be kinda difficult. --------------------  |

If you switch the intake manifolds you should be able to reinstall the EGR. But if you're looking for what car the 7A with no EGR came from it's probably a Geo Prizm, could be a Corolla too but I'm pretty sure most of those came with EGR systems.

or if you don't want to go through changing that, or don't feel there's a need for EGR, take that temp sensor off, and in its place just put a piece of wire shorting out the two pins on the harness for the EGR temp sensor, if its a 94-95 it will get rid of your CEL(check engine light)
