    I have a 2013 cascadia with a dd15 I keep getting code

    Eng 2 001 spn002791 Egr valve cntrl 14

    with a check engine light it comes on and off periodically We’ve already replaced the engine harness, ecm, delta pressure sensor, egr valve and actuator

    The code will disappear for about 5-6 miles and then the code still keeps coming back on do you have any suggestions what it can be? Really tired of throwing parts at it at this point and have no idea what else it could be

    Have you cleaned the doser injector. Carbon build up. 12mm and 14mm wrench. Carb cleaner wool scrubber

    At this point you have 2 options. 1 - Either methodically go through the troubleshooting steps that uncleal13 posted. 2 - Step 10 mentions to reprogram the MCM. That looks like the only thing in the steps that you have not done.
     
    Cascadia13 Thanks this.

    We reprogrammed it and same issue so I’m thinking it might be an electrical issue where the valve isn’t getting the actuator isn’t getting enough power or something similar

    Anyone think it can be the ACM?

    It did end up being the ecm and apparently the new ecm from freightliner was defective ‍♂️
