Hello, my names Joe and this is my first post here. I live in Sudbury, Ontario Canada. I own a 2010 chevy cobalt xfe with 357,000kms. It's a 5speed standard and runs great! This is a new car to me. I bought it only 2 weeks ago. Passed mechanical with no problems as it was well cared for by previous owner. The check engine light is on but the engine runs fine. Perhaps a slight hesitation when you first touch the gas. I read the codes with my bluetooth adapter and got P0013 - powertrain B Camshaft position - Actuator circuit (Bank 1) P0014 - powertrain B Camshaft position - timing over-advanced or system performance (bank 1 ) I usually order all my parts from rockauto.com Could someone tell me which sensor I need to replace and where it is located on my engine? A picture or video link would be great. This is the base model, no turbo or supercharger.
