The check engine light recently came on after an inspection at autozone i was told that the camshaft postion sensor was bad. I noticed the truck seems to hesitate during constant rpm ranges for ex. highway driving. I replaced the sensor and engine light was off with no hesitation during driving for one day. It has come on again and hesitation has begun once again. The new trouble code I now get is for o2 sensors and the camshaft postion sensor code is still registering. Any reply I am sure would be helpful. thankyou.

Do you know what the exact code numbers are you are getting? Just for starters did you may want to check the wiring for the CPS to be sure it's still plugged in and not frayed anywhere.
