O2 Sensor Heater Circuit Bank 1 Sensor 2, dealer says -front-O2 sensor needs to be replaced. So I did. CEL light comes back on after reset - same code . scanner shows Heated O2 ready, O2 not. Did I change the wrong O2 sensor?

 

TIA

This is the Rear O2 sensor....back by the tranny tailshaft. I had it on MY02. Subaru wouldn;t cover it at 39K. They said sensors were only covered up to 36K. I remember about $150 in 03 for that sensor. Hope it's cheaper for you by now.
