well i just did a gsr swap into my ej1 using the gsr engine harness and my check engine light is on for 02 sensor...i swapped 3 other o2 sensor and its still on...so my (Q) is...do i have to repin the o2 sensor wire...plz let me know asap

 

yes you need to pin in the 4 wire o2 for that motor.

 

bump anyone have any idea how to do this...i found the 4 wires on the gsr harness side but cant seem to figure the civic ecu harness side...i only have a diagram of the gsr and no diagram of the 92-95 civics

 

did you reset the check engine light when you put the new o2 sensor?

 

bump for some help im in the same boat

 

yes sir...i took out the fuse for 15-20 mins
