Car: 2000 Sonata GLS v6 w/ 55,000 miles
I recently bought this car and the check engine light came on the other night. The car has been running perfect, and the previous owner took meticulous care of this car. The car is originally from New Jersey and is now in Oklahoma.
The only difference I have noticed is that the idle seems to be a slightly rougher while it is parked. I say little as in there is almost no difference and none while driving. My understanding is that the code P1154- Bank 2 fuel control shifted rich is in regards to an O2 sensor located on the front passenger side of the exhaust manifold, is this correct? Is there anything I can do to prevent this from tripping again or is this something that tends to just "go out" as parts do?
When the car is cold, there is a slight high pitch whine from the transmission, but after you hit 20mph and the car warms up a little it doesnt do it anymore. Any ideas as what this might be? Any help would be much appreciated on these questions. Thanks.
