I/M codes on 99 Legacy E25DOHC to EJ22 SOHC


Recommended Posts

I have a 99 Legacy Outback with  manual trans. that has a ej22 with EGR engine swapped in it from an ej25 dohc engine. Four out the eight I/M codes are reading incomplete. They are catalyst monitor, evap  system maintenance, 02 system monitor, and egr/vvt monitor. Car also has one cel for 02sensor heater bank 1 sensor 1. I have driven the car for two 15 mile drive cycles.

 

Is having an ej22 with EGR  in a Legacy Outback manual trans car possibly causing the four I/M codes. I'm not sure where to start troubleshooting.
