Hey I am not sure what is going on with my car (I have a Honda Accord 2003 V6 3L), but of coarse right before the safety and emissions test the check engine light has to come on. When i tested it with the OBD2 reader it gave me five different codes. (p2243, p0134, p0154, p2254, and p0113) I replaced the O2 sensor in Bank 1 sensor 1 but the codes still come up. I was just wondering if anyone had any ideas as to what is wrong with my car?

Unfortunately, either you got a bad sensor or you replaced the wrong one. A faulty A/F (O2) sensor can trigger multiple DTC's in these cars, and can also set ones not mentioned in your post. The problem is the sensor.
