Click on the link below (but verify that the vehicle is correct for your application).
Expand the "Testing and Inspection" link and the P Code link under that. Select your DTCs and follow the test procedures that are in with the diagrams.

Might want to review the test procedures for all of them to determine if there is any commonality. Connector, circuit, etc.
