If you are getting these CEL codes you are the lucky winner of a civic with moisture in the exhaust!!! You now need a new Air Fuel Ratio sensor at the top of the exhaust. Luckily that part is usually $150+ instead of the cheaper O2 sensor ($100ish) in the middle of the exhaust.

also the service bulletin doesn't effect(affect?) our cars, just every other trim of Civic.

Re: P1172 PA200

pulled the air fuel ratio sensor
looked like this, seemed rather white instead of a darker carbon color of charring



Idled the car for about 20 minutes and drove it around the block and the CEL isn't back on yet.
