(posted in tech section as well) Im running a b20vtec in a 98 civic and i am using a converted cx harness. While using my obd1 p28 i throw no codes and car runs fine. However emmissions is here and i switched to my obd2 p72 and now im throwing a ckp code (code 4). My motor has all obd2 sensors/parts already installed even the sensor on the oil pump. This is my second distributor and it still throws this code. has anyone else had this happen to them?

 

good luck bro...its almost done
