I'm wondering if this is something I can do myself, and what part(s) I would need. Any information would be extremely helpful.
Figured out that Bank (1) Sensor (2) means Passenger Side Rear sensor. Bosch Part Number 15092 (dealer charges $290; Amazon has it for $<90 - gotta love online shopping!)
I'm guessing I might be able to replace it myself. Any advice or DIY instructions would be appreciated!
