Hey guys I've just finished some maintenance and had this code spring up when I started the car. I was messing around with the air filter and the piping for the AIR so I was just wondering where this valve was and what would cause the failure.

 

Probably a vacuum hose cracked, torn, loose.

 

Hmm...I was messing with some hoses when I was doing the A/C. Is this Valve A the valve on the passenger side AIR? Trying to track which hoses I should check and the Chilton's Manual is none too helpful.

 

I believe I actually mislabeled this one. It is a circuit malfunction for the Valve A on the AIR. Did something get unplugged?
