P0442/B2721/B2723 codes
The '"Check Engine" light came on on my 99 auto.
I cleared the history codes but, I found three current codes. B2721 and B2723 are Pass Key detection circuit codes. What does this mean?
The car starts and run fine. I can't find P0442. P0441 says Evap System no flow during purge. Is P0442 similar. How do I correct these issues?

First thing I would check is to see if the gas cap is tight. Use the search function on the tech page and search the codes. You will find lots.

For starters, make sure the pellet on the key is clean.
