Did you figure this out for sure? I have the same plug on the back of my b18a block, but there is no wire going to it, however I am not throwing a code.

I'm pretty damn sure that that is the knock sensor and the one below it is your coolant temp sensor. The coolant temp sensor has a rubber boot over a small coupler, the knock sensor is green. Thats how it is on my 1g B16

that's your ENGINE OIL TEMPERATURE SWITCH this is connects to your radiator fan control module. this is only found on US integra models 90-93. is part of the a/c system.
