Mvannessjr is correct with that meaning of code 41.
However, if your engine is a 3.8L, a code 41 may also mean "Camshaft Sensor or Circuit". I get this from the manual for my car (in my sig).
In my case, I had a code 41 for quite a while. I replaced the sensor, but it didn't do any good. I did some research, and found that it may be the magnet that's attached inside the timing cover on the Cam Sprocket. As the cam sprocket rotates, it makes the magnet pass by the sensor and sends that signal to the computer.
Using lights and a mirror with the sensor off, rotate the engine manually and look inside the sensor hole untill you see where the magnet belongs. The magnet may be broken, or completely missing.
According to my Haynes manual, the magnet should be square with a metal backing that bolts onto the front of the sprocket. However, this wasn't the case. The correct magnet was smaller, shaped as a cylinder, and encased in plastic. It snapped in place in a small hole in the sprocket.
Once the magnet was in place, code 41 never returned again, and I gained some engine power I never new I had lost. If this is your problem, you may find pieces of the old magnet and/or plastic housing sitting in the bottom of your oil pan.
Good Luck!
