SOURCE: 2004 300m where is the vapor canister purge
On the drivers side under the hood toward the back not to far from the the strut housing.If you have the new one try to match it up by the looks :)
SOURCE: I need to locate the canister purge valve and the
look above the spare tire under the back of the box
SOURCE: 2006 gmc sierra 1500 4.3 . check engine light on.
More than likely the evaporator vent valve.

There is a purge solenoid for the EVAP system and it is item no.# 1 shown in the diagram below. You have to follow the purge valve vacumn hose to find the charcoal cannister if you need to inspect.
I have included a description of the EVAP system for your understanding.
EVAPORATIVE EMISSION (EVAP) CONTROL SYSTEM
The EVAP and on-board refueling vapor recovery (ORVR) system consists of a fill vent valve, fuel shut-off valve, fuel cut (roll-over) valve, fuel liquid/vapor separator, EVAP canister, EVAP canister purge solenoid valve, EVAP canister close valve, vacuum relief filler cap, and connecting lines and hoses. ORVR system is designed to prevent the release of fuel vapors during refueling. During refueling, as fuel enters the fuel tank, a vacuum is created in filler pipe, drawing air into the filler pipe and tank. Fuel vapor in fuel tank is then forced to the EVAP canister via the fill vent valve and the fuel liquid/vapor separator. A fuel tank pressure sensor is used for detecting EVAP system leaks by comparing pressures inside and outside of fuel tank.
EVAP Canister Purge Solenoid Valve
Fuel vapors are vented into the EVAP canister during refueling and when ignition is off. When engine is at normal operating temperature and engine speed is greater than idle, a thermovalve opens and allows vacuum to open the purge control valve. Canister vapors are then drawn into the intake manifold for burning during combustion. The purge control valve is kept closed during idle and engine warm-up to reduce HC and CO emissions.

Evaporative Emission Purge Solenoid
Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.
