OBD code deciphering help

Ok, so I have been messing around with this for way too long.....

I did a KOER (Key on Engine Running) scan test on my 95 Splash 4.0, and got this code
P1143-which says it is Air Assisted Injector Control Valve Range or Performance
Basically i would like to check the harness on whatever this thing, it, but have no idea what or where it is to begin!!!
Can anyone shed some light?

I also got P1401 and P1409...so I think I am going to change the EGR vacuum regulator, to see what happens...then It might be out with the valve itself....any thoughts?
