My 03:TB has just over 230k and the blow by is bad. I'm sure it's what is making my Cam shaft positioning sensor to throw the error code. I have replaced that sensor twice in the last 6 months. I have also replaced the Cam shaft actuator. She is still throwing that code. And before you ask yes I did clear the codes. I always clear then ads have it throw them again to be sure it's not a false code. When it throws then the second time I fix it. But these two parts along with misfires seems to plague this model. My buddy has the same truck, 2 years newer and his has constant misfires too. I mean I got to where I can go from a closed hood to a closed hood and replace all 6 ignition coils in under 30 minutes and that was before I actually had to get into mechanics to keep a truck with 230k+ on the road. Is probably under 20 min now.
What the hell is causing this coverage code for the cam shaft shaft sensor.
