Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Yes you can attempt a cleaning. I would remove a vacuum line right behind the throttle body, Start the engine and slowly pour a complete bottle of sea foam through it. This will fog the intake and clean it out including the combustion chamber. This may fix this code but will for sure make the engine run better. Once done you will need to run the engine hard a couple of times to blow out the gunk. It is going to smoke alot. Once done you will need to remove the negative battery cable for 15 minutes to clear this code and any you caused with the open vacuum line. After a week of use if the light has not come back on then get it checked again. Below is a file explaining what this code means.
This is my 1st answer, but does not have to be my only answer. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. Please let me know if you are pleased by selecting a star rating above or by replying and saying your pleased. Not rating or rating 1-2 stars does not benefit you nor me in any way. Follow up and reply as often and when needed, there is no extra charge to do so.
Glad I could help.
Most all hoses to the intake manifold are vacuum hoses, any of which will work. Some are just pushed on and others have a locking clip and connector and some have a squeeze clamp.
This looks like a vacuum line.
You can disconnect the line at the brake booster if you can not get it off at the throttle body.
