There are several items that can cause this fault code to pop up, one being a vacuum leak, loose timing belt, dirty throttle body, or faulty MAF. The most common cause is a dirty throttle body, you can clean it out by removing and using an air intake cleaner. Once you reinstall, you will need to do a capacitor discharge to clear out the learned value. Disconnect the battery cables, negative first then positive, while they are both off, touch them together, this will cause a complete reboot once you reconnect them. You need to reconnect them positive first then negative. Then clear out any fault codes and drive the vehicle for a short time to verify the codes don't come back.
