The Service Engine Soon light just lit up on my 97 Continental, I am assuming it is from an oxygen sensor, how do I check codes to make sure that is the problem? Is there a way to have codes flash on the dash or should I just go to AutoZone and have them check it for me?
Alternatively, you could pick up one of those little Bluetooth OBDII readers online for ~$15, and use the app "Torque" on any Android phone. It'll read codes, as well as status on most of the various sensors.
