I have an 06 Sonata with the 3.3 engine with 26000 miles and the check engine light is on. It runs fine and everything seems ok. I had it checked and it reads PO504, a brake switch A and B correlation issue. what could cause this and are there any recalls or tsb on this issue. any help is greatly appreciated.

Go to http://sonata.jerrystout.us/ and under misc and DIY you will find OBDII codes, however, I did not see your code listed.

Could be a couple things. . . Bad Stop fuse, short in stop light switch signal circuit, Stop light switch, or a problem with the ECM
