The engine may be hard to start and/or illuminate the Check Engine Light with code P0340/P0344 stored. The common repair is to update the Powertrain Control Module (PCM) software. In some cases replacement of the camshaft position sensor may also be required.

I was having trouble with my truck when it got up around 4500 rpms and the truck would jerk around and then basically stop. After restarting it i went to an auto store where they told me it was the cam position sensor. I changed that and am still having the problem. I need some help if anyone has it.
check Engine light and Po340 code that will not clear
Code p0340, hard starting and failure to quickly accelerate
