ADAM
THE PURGE SOLANOID IS ON THE ENGINE WITH A RED CONNECTOR ON IT. IT IS LOCATED ON THE REAR OF THE ENGINE ABOVE THE REAR VALVECOVER. YOU ARE ACTUALLY LOOKING FOR THE CANISTER VENT SOLANOID AND IT IS IN THE REAR OF THE CAR AND THEY FAIL OFTEN. GET THE PART FROM G.M. AND THEY CAN TELL YOU EXACTLY WHERE IT IS. THE G.M. PART IS UNDER $30.00.

Change the evap vent solenoid canister located near the master cylinder on the right side of the engine or your hoses may be cracked. Good luck!

Hello Reina.
It isn't going to hurt anything unless your fuel tank is leaking fuel. In which case you should get it fixed.
It could be a fuel cap and if it seems loose or worn you should replace it anyway. It may cure the problem.
It may take a while for the light to turn off though, as it will need to run the test and pass before it goes out.
If you need more help, leave a message and I will return to assist.

Testimonial: "If it is my fuel tank leaking, how would I know. Would I smell gas?"
SOURCE: where is the evap purge solenoid and canister at
purge sol should be under the hood with evap lines going to it. canister is under the car near the fuel tank or on it.
Can't tell you any more than you have on printout
Need a repair shop to diagnose what you were given

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.
