If the engine is running without any problems then The fault code which has flagged the checked engine light will either pertain to the upstream O2 sensor, a drop in catalytic efficiency, an EGR issue, or maybe even an EVAP issue.
A lot of EVAP issues can be resolved by simply ensuring that the fuel filler cap is on securely, otherwise a vacuum leak will be detected in the system and the check engine light will come on.
A drop in catalytic efficiency (P0420) is usually temporary and will stay away after a reset.
EGR issues can sometimes be rectified by removing the EGR valve and cleaning it, and the ports on the intake where it was sat, but there are occasions when it has to be renewed.
The O2 sensor issues are a wee bit different. There are a number of fault codes which relate to the O2 sensor, and which make the O2 sensor look faulty, when the O2 sensor is actually attempting to rectify a problem from elsewhere and isn't faulty at all. However, they could also be due to a fault with the O2 sensor. Basically, further checks should be made before condemning the O2 sensor should the fault code relate to the sensor.
Have a code read done and then have the codes reset and see what comes up.

Horsecrap...go to an independent transmission dealer after you call the extended warranty folks and complain!
I can count the number of Honda transmissions that go bad before 300,000 miles on one hand.

po505 idle air control if this is the code all hondas do it eventully, small problem easy fix u have 2 choices either remove the idle air control motor and clean the inside of it u will find it's black and the spring inside is stuck clean it with carb cleaner or gum cutter any parts store will have this it's a dirty job it will work for awhile but to replace it is recommended its not expensive for a new one which u can get at any autoparts store autozone,advanced,napa etc. there is only 2 bolts in most cases maybe 3 i doubt it though if u go online t google and type in th eyear make and model and engine size in ur case it's a 3.0 v6 and look for idle air control locations u'll find it to do this job a shop will charge u anywhere from 100.00 for diag to retrive the code plus the part and the labor so about 250.00-375.00 it will only take u honestly maybe 15 minutes to perform only tools needed are a 10 millimeter wrench there is only 1 connector to disconnect and ur done if u do this u will still have the check engine light because u have not cleared it from the computer to do this just disconnect the negative battery terminal (the black one or has a neg sign - don't disconnect the positive side +)for 5 minutes then reconnect and the computer will have reset no more light. good luck it really is that easy

SOURCE: check engine light is on,
Could be as simple as a loose gas cap or cap seal or a bad o2 sensor. A falty cat. converter will also cause the check engine light to come on. Either way, you need to go either to a dealer or some auto parts stores will plug in the dioegnostic sensor and can tell what is wrong. your gas milage will suffer until you get this fixed. Your engine computer uses the inputs from your o2 sensers to adjust the fuel air mixture of the engine for optimum engine performance.

i think this is a common issue with Honda and the accord models. unless you are getting any engine warning or seeing problems or losing power I would not worry and ask Honda to reset processor at next service.
