wassup fellas im a newbie to the honda forums Anyway I have a B16A2pr3 OBD0 swap on my crx> Its throwing a cell I check the light on the ecu and it blinks once and theres a pause for 4 to 5 seconds and it blinks again. I look up the code and apparently is the 1) Primary oxygen sensor- Defective circuit or unplugged/ Defective sensorI have two o2 sensor is there a way to wire just one o2 sensor for it to work properly. If not which is the primary oxygen sensor and where can i get one? Any help will help thanks

 

bump

 

both sensors are needed for the obd0 b16 ecu. i would check to make sure both wires from the sensors are making it back to the appropriate spots on the ecu.

 

I'll check.. if it is the sensor where can I get one? because all I found is a 4 wire oxygen sensor. and the obd0 is one wire

 

Anyone knows where I can find the one wire oxygen for the obd0 b16a? so far I only found 4 wire oxygen sensor..

 

just get one from an 88-91 civic/crx. they are 1 wire sensors..

 

will that work on a b16a??

 

yes, size and thread pitch is the same.

this should help as well

 

Heres the ECU diagram to go with the above pic

 

Thanxs everyone for the insight. I change both of my o2 sensor my car is runing smooth now that might have been the problem. replace ur o2 sensor and ur car will run better
