I have 6 error codes on my Cayenne 06.

Question

Bank 1 sensor 1 replaced recently.

These error codes pop up. Codes identical for both banks. There must be a short somewhere.

Answer 1

P2626 oxygen sensor ahead of catalytic convertor Bank 1 -pump voltage line -open circuit

P2A00 electric fault in oxygen sensor ahead of catalytic conertor bank 1

When there is a 02 sensor that set a code you will set additional codes, these are just informative, the code you have is the 02 sensor having a open circuit, if you can replace the 02 sensor for another good working one you would cut the time , there you can retest
