I threw a chek engine light last night after looking around the engine bay i found what looking to be a pig tail for aa sensor just hanning down on the driver side of the bay. underneath the break master cylinder. the pig tail is blue and is clipped into the the cradle with only about 2 inches of play. i looked around and cant find any where fot it to go...Any ideas ...my thoughts as of now are is it pluged into some kind of extension that went to the exhaust for an o2 sensor...any help would b great ...thanx
or evene a wire schematic would help.
