View Full Version : Emission sensor under warranty?

11-22-2008, 12:31 PM
I have an 03 Subaru Forester with 39000 miles serviced Aug 2008. Scanned and found code P0030. Dealer installed new front A/F sensor. Is the A/F sensor the same as an O2 sensor which code P0030 addresses, and should this have been under factory/federal warranty?
