I have a 91 integra. The O2 sensor is mounted at the top runner of the exhaust manifold. I just picked up a jdm ctr manifold and the O2 bung is on the collector just before the cat. I need to know if just lengthening the wire for the O2 sensor and putting it down there will be ok or if it will throw codes or anything.
I was told that the O2 sensor I have is a 1 wire type, and must be heated by the engine to work properly. What I need is a 4 wire sensor that will heat itself up to the proper temp and run the other 3 wires to wherever they're supposed to go. I've never heard of this before so can someone verify this to me and tell what I need to do?? TIA
