So tonight - on my way home I get the DING DING - and see 'Reduced Engine Power' on the dash. Then the ABS light came on.. So I pulled over - as you cant even go above 2k rpm's when this happens. Re started the truck 2 - 3 times and it finally would rev up normally. I went back to my shop, and pulled the codes and got the code P1516 "Truck is drive by wire" I cleared all the codes - and its been fine since. Now this happened to me once before but it was when the truck was parked outside in -20 some off weather.. and I think the throttle body actually was froze.. I never had this issue since then. So Not sure what the issue is but I take it as it has to be one of a few things - the pedal sensor or the servo on the Throttle Body going bad.. A glitch in the system? I don't know. Anyone else have this? I also have NO idea about why the ABS came on - but I got the codes of : C0291 and CO237 And lastly - this is random - but when the truck went into reduced engine power / limp mode the doors unlocked.. is this a normal safety thing? Kinda weird!
