I changed my camshaft sensor which was quite easy to do with the help of youtube. Before replacing the sensor, I would first clean it and see if that solves the problem. My original camshaft sensor was full of oil but this was after 150K miles. If you do end up replacing your sensor ($15 part), there is nothing else to do but clear your obd tester. A really simple job. Good luck!
