Hello, I have a 2007 G6 2.4L. Lately my car has been bogging down with a loss of power, and doesn't seem to shift smoothly. My friend used his scan tool and said the car was throwing a code for a cam sensor. I then find out that the car actually has TWO camshaft position sensors, yet I can only locate the one right on top of the engine under the plastic cover. The parts store I called is telling me there are two on this car, yet can't tell me where they are located. Does anyone know if there are actually two, and if so, where the other is located?? I great appreciate any responses. Thanks!
