2008 Impala throwing P0340 code

[sroney]

I have a 2008 Impala with the 3.9L engine. The car has ~51,000 miles. Tonight, the check engine light came on, and the OBD scanner is showing a P0340, Cam Position Sensor A Bank 1 Ckt Malfunction.

Where should I begin with this?

Thanks!

1) Reset & clear code
2) Monitor
3) Also look at Similar threads at the bottom of yours.

Doe's Ice, snow, rain, or a car wash play a factor?

At this point I'm not sure what may or may not cause problems. The light just came on yesterday. Can you tell me where this sensor is on this car? I want to start tracing circuits, etc.

Thank You.
