Depending on the cause of it, very much so. P0011 indicates a fault in the camshaft position sensor circuit, and it may be the sensor itself or the actuator. You can try throwing a new sensor in, but, if that's not the cause, you'd just be wasting money. Actually diagnosing this condition requires an OBD2 tool which actually has command functions - we're talking something like a ProLink IQ, Snap-on Solus or Verus, etc., where you'd be looking at $1400 or more for it. You should get that taken in and checked out.
You will need a code reader. Your local auto parts store can sell you a simple one for $60 to $80. It will come with directions and a book of code definitions.

In the trunk, under the carpet, on the left side.
I am sorry but you do not without the proper equipment.
A lot of parts stores will check it for free
Check engine is an error. You have to go at a garage to see what is the error code, then correct the problem.
Trouble code P0011 means:"A" camshaft postion-timing-over-advanced (bank 1)
On the engine block on the top front just behind the water pump on a machined surface the code will be stamped.
It means the engine didn't warm up to the correct operating temperature. Thermostat is probably stuck open. Replace the thermostat.
No, you need an OBD2 scanner in order to retrieve the code.
