It may help to read the system description and other info in the FSM. Plus there is usually a detailed explanation of what the different DTCs mean. Great resource for the DIYer.

Do I check the voltage of the 02 sensor to determine a bad sensor ? and Ill try to switch the 2 sensors and see if the code changes. ill also check the exhaust pipes for any leaks.
