2006 SONATA V6 3.3L - P2273 Engine light issue
I have check engine light comes on first and after driving a few hundred miles later,
light goes off. I drive the car for awhile about a few hundred miles and light comes on
again. Basically on an off. AutoZone looked at it and got an error P2273 - it means
oxygen sensor stuck rich. They told me to keep fuel tank cap tight. or something else
may be defective. I have been driving last two years like this having engine light on
and off. I do not see any engine performance difference. Any ideas?
It is likely an o2 sensor. The code scan should tell you which one.
Thanks for the quick response. P2273 code is the one I get. do you know which sensor might be the one?
all my research says drivers side bank 2 downstream of the cat. you may have to consult a Haynes manual or call a dealer service dept and ask.
