Was driving and the Eletronic Throttle Control came up. Pulled over tried a few things but no change i did not have my scanner with me. I limped back home and parked it for 2 weeks. Got back home and pulled the codes P26A7 Engine coolant Bypass valve 1 position sensor circuit high , P2683 engine coolant bypass valve control circuit high , Po12D Turbocharger inlet pressor circuit high , P2455 Diesel Particulate filter pressure sensor high -pending , P2681 Engine coolant bypass valve control circuit open-pending , and U1428 Inaccurate Engine Torque received , Ok i cleared all codes truck starts up and is running fine go about 5 miles and then it does the same thing. Where do i need to look first something is triggering all these at the same time , i just dont want to start replacing a lot of parts. Thanks for any help you can give me or point me in the right direction.
