can someone tell me what this is??? i try to clear DTC's through evoscan but the code keeps poping up.

only think i can figure what this is i added the test pipe which i knew the cel would come up for 02. Its an ichiba test pipe.

If its the normal code for adding a test pipe i wouldn't be as worried but i thought the code was P0420?
