Check Engine light code P1416

Hi all. 98 Trans Am 50k miles. Car runs fine but when i got the check engine light my scanner read code P1416 (aux emission controller). I erased the code and the car runned 1 1/2 day until the Check Engine light came back on again with the same code. Any ideas on where to start?

I did some research and this code is for Bank 2 of the secondary AIR system. Lots of the people that had this problem said to replace the AIR check valves. I did replace them since they were pretty cheap. I erase the codes and so far so good. I'll keep you guys posted.

Good catch, and thanks for the tip. :thumbsup:
