i just swaped in a obd1 b16 into a obd2 hatch and im throwin code 10, 20, and 41 .. i know 41 is bad main o2 right? but i dont know why its throwing 10 and 20.. also when its in low rev like 1-4k i car sputters, like its bogging (would that mean ecu problems?) cuz the engine was com tested at 240 all around so i dont know what could it be? any help/ input can help thanks

 

up for help!

 

I was throwing code 10 also. I cleaned my Intake Air Temp. Sensor, and the problem went away. If cleaning doesn't fix you might need a new one. I'm not sure about the code 20. Sorry if this didn't help much.

 

what did you clean it with?

 

Code 41 is o2 heater (seems pretty common on swaps). Buy a new o2 sensor and call it a day (i bought an NTK from oxygensensors.com).

Code 10, as RippinVTEC said, clean-out your IAT w/ something light (green-stuff maybe) and go from there. If not, you'll need a new one.

Code 20 is electrical load detector. Your (archives) search for Code 20 electrical load detector returned 10 results... i picked one thread that had some good info and a pretty good link in it. Hope this'll help. https://honda-tech.com/zerothread?id=931523

 

"green-stuff" is that an actual brand? or just an description?

 

I think you blew your alternator fuse, under the dash (41 and 20 occur because of this)

As for 10, clean the iat connector and put dielectric grease on it.
