Have a 96 hatch with b16a2 throwing codes. Just installed a new harness and throwing codes 3,6,7, and 10. Is their something i should be looking for everything is hooked up. Ran bad with old hacked harness and installed an unhacked harness and still troubles.

 

A B16a2 engine is OBD2b and your 96 Civic is OBD2a. How did you deal with these differences for the swap?

Reset the ECU to see whether all codes repeat.

Triple check for swapped sensor connectors.

 

So the car has a obd2-obd1 adapter at the computer running a p30. Also before the harness swap it was throwing codes but i dont know what codes, i know one was the iacv but its not throwing one for that now.

 

replaced tps, map, and temp sensor and still running the same. guy told me today it was idleing bad when he bought it. So im starting to think the adapter harness or computer is crap. Gonna ohm out the sensors and see what happens.
