ok guys so ive been having this really bad ticking in my 00 z and its been sounding like its been coming from under the drivers side valve cover so i went to take everything apart today and noticed this sensor with two lines coming out and the line to the right was snapped off and its directly over where the sound is coming from. can anyone tell me what sensor that is and that those two lines are? also where did the line to the right go that is snapped off????

If i am looking at the picture correctly, it looks like the vacuum lines going to your AIR pump solenoid
