cam position sensor

Hi, no, your cam position sensors are not bad. No codes will tell you a part has failed. They'll lead you to areas to focus testing on. Often times, camshaft position sensor related codes can be related to engine timing issues, or a stall caused by another component issue. As a result, replacing them would indeed have zero effect on your concern. Which engine do you have in your vehicle? Hard to go on not knowing if it's a V6 or one of 2 possible V8's.
