Getting error code P0496 based on engine light turning on.

Resolved Question:

Getting error code P0496 based on engine light turning on. I believe it is the vapor canister vent solenoid, or the vapor canister purge solenoid. More than likely the purge solenoid because I am having trouble starting the vehicle. This car only has 60,000 miles on it, it is a 2007 Cadillac SRX. I fear taking it to the dealership because I don't want to be raped on the price. What could I expect to pay for these repairs? Do you find this a viable synopsis of what the problem is? (def not gas cap), and could I do the repairs myself?

This code sets when the computer senses continuous purge of the evap system. That, along with the fact that you have a hard start adds up to the purge solenoid. This repair would run you about $100. The part # XXXXX XXXXX and lists for $35. You can easily do this repair yourself.

 

The arrow in the below illustrations points toward the front of the vehicle.

    You are the FN man!! Thanks for your help, I hope that this works, because I depend on my care for driving. Does it really matter if I get a GM part, or can I go to a local Advance, Autozone etc to find a part that will work as well?
    Expert:  Dave Nova replied 4 years ago.
    If your local parts store has the part, it will be okay to use their part. The part # XXXXX supplied is the original GM part.
