ok know what the code is just not sure how to clear the problem. 93 civic dx did not have code before doing y8 swap in car. p28 ecu shows this code but the po6 does not. could this be the p28 ecu or another problem? Might be stupid question but I have asked several people and they scratch their heads.

 

not completly sure if the dx uses a 1 wire or 4 wire o2 sensor, if it uses a 1 wire then you need to convert to a 4 wire. somebody correct me if im wrong.

 

It is a 4 wire o2

 

Any advice would help with this if anyone has an idea.
