I did a D15b in a 93 dx. Swaps runs good but is tripping a code for the 02 sensor. I had to use the four wire O2 sensor because the 1 wire O2 sensor would not plug into the harness. I am running a P08 ECU. If I run a P28 would this solve the problem.

 

it should fix the problem to run the p28 ecu
