CEL said p0012, changed camshaft position sensor. 3 days later... I would say about 6 drive cycles, CEL again, p0016. I did notice the mechanic pulling a sensor off the top of the motor, sorry I am not mechanical, and it stopped the clicking. He doesnt know what to do now. Any help would be appreciated as I dont have 2k to pay the dealership knowing all the bs they will tack on that "needs fixed"
