i know what they are, (9-cyp/cylinder sensor, 20-eld sensor, 22-vtec oil pressure sensor) but damnit...can't figure out whats wrong

after 6 months of doing nothing, i finally got around to wiring everything up with blown90hatch's wiring harness...

anyway, i've heard that for code 9, it could be a faulty distributor. from what i've read, code 20 doesn't really do much as far as performance, but i still want that light to go away (i have to smog my motor). code 22 could be a number of things ranging from dirty/too low or too high oil levels to a faulty sensor....or it could all just be my wiring

what i'm asking is how do i check my wiring? i'm not an electronic genius, so pls help me out and explain what you mean by "check continuity" or "see if there's a load"

thanks

btw i originally had a 90 civic si with a harness rewired for an obd0 b16a (obd0 dizzy and the 2 o2 sensors). now i'm running a p30 ecu with obd1 dizzy and 4wire o2 sensor
