Lawsonmh15 Posted July 15, 2005 Share Posted July 15, 2005 Well, in my never-ending quest for knowledge of my 99 Legacy SUS; I found something quite odd. I was looking for the Driver Door Power Window relay, (where is that sucker?) but instead, I found an unconnected wire below my dash. So... Yeah. Obviously I hooked that sucker up to see what happened, and the end result was a blinking CEL. WTF?!!! This is also accompanied by weird clicking noise with they key in and turned to acc. ( as far as I can go without cranking). So, I turned it off and disconnected the wire which obviously solved the problem. Today I was at a local Checker grabbin' a fuel filter, and I figured I'd have them throw a code reader on. Without the wire connected, no codes came back. With the wire connected I get a PO130 (O2 sensor). Here are my questions. The wire I found is two conductor with a small green spade connector. (Initially I thought the wire went to the seatbelt sensor due to the identical connectors.) Does the wire more than likely go to the O2 sensor? If so, what's its flow? (i.e. O2 -> ECU -> OBD port)? Also, with that wire not connected, am I basically bypassing the O2 sensor? If so, why isn't it negatively affecting me? If not, what gremlin is causing the PO130? Judging by the weird relay type of click when connected, I'm inclined to believe that the wire is shorted at some point. If not, please explain. Thanks in advance, Matt.
