I have an engine light and I can't pass my emission test. I downloaded at Auto Zone and they provided me the following codes:

BB1 - A/F ratio concern 1
BB2- Air Leak near HO2S (heated oxygen sensor)
BB3 - Ignition system concern
BB4- Faulty catalytic converter

Any help is appreciated, what can be the problem and what needs to be replaced to correct? Thanks

 

Those are not codes. Those are the possible causes of whatever code you have. The code will be 4 digits following the letter "p"

 

Last time I went to AutoZone the guy told me the Pxxxx error code number. But when he went inside & printed it out, the printout was pretty strange. Way on the top it said P1234 (whatever the number) and then it was a really REALLY long printout with the meaning of that number for any & all different car companies. He tore off the section for Honda, so I never got the very top where it gave the actual code number.
