Unhappy Check Engine Light On
My check engine light triggered today so when I arrived home I grabbed my OBD 2 and plugged it in it gave me 2 trouble codes, PO172 and PO175. It registered Bank 1 and Bank 2 , System too Rich. I'm assuming its Oxygen Sensors? I have a 2006 IS 350. Anybody had this type of problem before? Much are the sensors? What shall I do?

Over night did the system reset and is the CEL still on?

I've got a '06 350 myself; what mileage are you at though?
