Honda Civic 99 DX P0402 EGR Flow excessive
Hello all,
Im trying to help my father fix his car, he has a 99 DX Civic and hes getting an error code of P0402 which means EGR Flow Excessive. I have tried googling this online but cant seem to find anything relating to this, I have even read that the 99 Civic doesnt even have a EGR Valve. Any help would be greatly appreciated.
Thank you!

Now that I think about it since my car does not have an EGR Valve. A few months ago I replaced my IAC Valve a long with a new throttle body, i got this part from a salvage yard. I am wondering if replacing those two could be the cause of a faulty EGR P0402 Code? Any help would be helpful.
