SES diagnosis Alright, I've been getting an SES light lately, it's code P1416, which is secondary air injection (AIR) system bank 2. So this means if I'm standing in front of the car facing the engine, the problem is somewhere on the left side, correct? What is something pretty common that causes this? I found a loose clamp on one of the hoses and tightened it, but it still came back on today. Any ideas?
Re: SES diagnosis ON my 99 Z when it was about a year or two old it had to have the check valve replaced on the passenger side. MAYBE <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />
