How many o2 sensors should a 1990 Integra w/b18a1 have? It has an aftermarket header on it for a b16 motor and it has 2 o2 bungs in it. I'm pretty sure it should only have one... just need someone to verify.

Thanks.

the car only has 1 o2 senor because its an ob1. you should be able to find a cap to plug the other hole

ok, I am getting a cel code #67, which is the cat. There is only 1 o2 and it is before the cat. If there isnt one after the cat, how does the ecu know to give a catylist code.
Sorry for all the questions, but im just a little confused.:thinking:

its 1 before the cat the second bung is on a aftermarket header is normally for your wideband o2 for tuning.

when some run this header wich is for an obd2a they have 2 o2 sensors. plug either one but if it still kicks you may have to get the sensor up out of the exhaust flow a bit with an o2 extension made from a spark plug fowler wled in. or just run a thin nut up on the senser then rethread it in cause sometimes headers disrupt the air fuel oxegen richness and kick this code
