well i did a swap and i had to extend my o2 sensor wires to reach the 02 sensor plug. After i did all that and hooked it up the plug i still have a engine check light...i then checked the ecu codes and it said that i had a code 1 and code 41, which are both oxygen sensor codes. What could i be doing wrong?

 

i think the o2 sensor wires need to be shielded to work properly

 

What is the swap that you did? I just put a b18c into a 2k hx and my wiring harness conversion harness wasnt wired correctly in a couple places. After i corrected it it worked fine. I didnt use shielded wires either. but I was only throwing code 41.

 

its a b18b into a 95 ex...how do i make them shielded?

 

Since you have two 02 wires, I have herd of people hooking em up to the wrong. They switch em and then they throw the 41 and 1 codes, cause there were interchagned. Just a suggestion.

its obd 1...so theres only 1 o2 sensor...thanks for the suggestion tho
