Code P0010 - Camshaft Position Actuator (valve) Sensor. on 2009 Chevrolet Malibu

Where is it located. Is it just above the oil filter? I understand that there are 2 of them. An intake and exhaust? The service engine light is on. This came on right after I changed the oil. I do change my oil every 3,000 miles. Help.
