Posted: Tue Jun 07, 2011 5:25 pmsubaru diognosed a/f ratio sensor po31 failed . quoted $768 + labour. can someone point out which sensor this is,and where I may purchase same.
Do a search under "o2 Sensor" you'll find pleeeeeenty on the damn things over in the 2.0T or 2.5T engine sections.
By the way do NOT pay what Subaru are quoting.
