hey guys, two part question: 1. what is the best way to get to bank1 sensor1 to replace it?
2. where is the suction pump located on 2.7t 01' ?

 

1. don't know
2. it's behind the engine, middle, between the engine and firewall.

 

1. Oxygen sensor socket, 3/8 drive swivel, long extension, big ratchet, big muscles. That bitch is tight and you lose alot of torque thru the swivel and the extension.
2. If your talking about the secondary air pump, thats the correct location.
