Ok I have searched and I know the O2 sensor has been discussed alot here.
I just cant find a clear answer.
The car is an 88 CRX DX. Hasport harness with a PR3 ECU chipped by Katman at Jdmhondaparts.
I have these two plugs that I think go to the O2 sensors. I also am not sure if the chip in my ECU is for one or two O2 Sensors. I have a DC header with a bung, and a bung in the exhaust after the header.

Should I run one or two?

Are these plugs both to the O2 sensors.

Thanks for any help.

 

anyone?

 

?

 

I have the same wires on my car. I know for a fact that the clear/yellow one is for a single wire o2 sensor. I don't know what the green one connects to, maybe somebody else knows about this one, but I'm pretty sure it's an o2 sensor as well, another single wire one.

 

obd-0 B16A's need 2 o2 sensors, one reads pistons 1 and 4 and the other reads pistons 2 and 3.

thanks crx_88_si,

A picture is worth a thousand words.

 

Not to jack but

Primary would be 1 & 4 ? C16 ?

Secondary would be 2 & 3 ? C8 ?

 

when i go to the parts store to get THE O2 SENSOR what am i going to look for TO GET?

 

just ask for one for your car, any 1 wire will work, the stock civic/crx ones work fine
