Okay I just got a DC sports 4-2-1 header for my REX, and as I began take of fmy stock manifold I noticed that there are 2 O2 sensors going into it but the header itself only has one spot for an O2 sensor I was told that it was possible to rewire it so that I was only running one sensor, is this possible without throwing a code and if so how is it done?.Oh and the car is OBD1.

 

I thought obd1 cars only used the 4wire sensor (well and the one wire sensor on certain models). I thought only 2 plugs were used on the obdo b16a when using the pw3 ecu (I think thats the ecu ).

What ecu are you running?

P30

 

haha not a guiness on ecu codes. whats the p30 from?

 

From an OBD 1 B16

 

is the a del sol or jdm one?

 

JDM one, I 'should' only have 2 O2 sensors, on ein the original header and one in the cat correct?

 

uh oh. I never messed with JDM ECU and o2 sensors so far. I apologize but I can't help you.

I was under the impression just obdo b16s ran the two on the exhaust manifold and obd1 had just the 4-wire.

(obd2 would have one on header and one on cat)
