Hello Sentra fam! I have an 03 spec V. Im currently battling the dreaded P2135 code. Upon inspecting my wiring harness i found this connector and can't figure out where it connects to. Single green wire by the oil pressure sensor. Right above the pressure sensor, theres a threaded plug. I thought a coolant temp sensor should be there, but nothing on rockauto shows a coolant sensor that would fit that connector. Im thinking power steering switch but couldn't find it from top or bottom. Does anybody know where i should plug it to?
