The Check Engine Light came on. Autozone read it as a P2197, Bank 2, Sensor 1, Stuck Lean. The Service Writer at the dealership said it's the "fuel/air ratio sensor" and they will replace it under warranty tomorrow. There's a slight rotten egg smell from the exhaust sometimes, and the engine runs a bit rough at idle.
It's been lit since Thursday, 4/5. "Stuck Lean" -- is that a problem for the cat. or injectors, or ___?
I couldn't find the P2197 code in any of Lon's Garage code listings, and I haven't seen any posts on the 02 sensor going bad on a 2006. Milage is only 13,600.
What would cause a sensor to crap out so soon? I read that these things sometimes die in pairs.
