Diagram for where the canister purge solenoid is located on a 2002 chevy impala

3.8 liter - remove the engine cover. As your standing in front of the vehicle it will be located on the passenger side of the engine inbetween the intake plenum and the valve cover. It will have three wires going to it and to vacuum hoses.

3.4 liter - it will be either mounted to the intake plenum in between the throttle body and the EGR valve. It could also be mounted to the coil/module bracket on the backside of the motor in betweent the motor and the firewall. I think its new enough that it should be in the first location I described.

Also on the under side of the hood (if its the original hood) there should be a sticker with a vacuum diagram and the basic location of that solenoid. The sticker could also be mounted on the upper radiator support or the strut tower on the passenger side.
