I pulled out the other day and was accelerating, when the CEL came on and the truck went from 40mph down to 30mph for a short distance. I ran a code check on an ODB II scanner and pulled a P1689 (No communication between ECM and Injector pump module), a P0234 (Engine overboost), and a P0500 (No vehicle speed sensor signal). Then that night, I got on the accelerator at a redlight and it accelerated to 35 smoothly, then a few audible pops
came from somewhere in the drivetrain. I got stopped at a train and hopped out to check that all the u-joints and parts of the driveshafts were tight.
Could this be my tranny causing the codes to pop up when the truck goes into the temporary "limp" mode? :shrug: I had the injector pump and lift pump replaced just over 3 months ago.
Thanks in advance for any ideas.
