    Perform the flash first. We have have marginal success with cleaning EGR valves. I hate to see people waste money so I usually recommend replacing it. Very often the cleaning is unsuccessful.

    Check for the latest software in the ECM, there is a flash update for this code. Check TSB 18-005-13. 

    2. If the code returns, check and clean the Exhaust Gas Recirculation (EGR) valve and passages. Next, clear the codes, test the vehicle and check for codes afterward. If the codes return, replace the EGR valve.

    When the egr valve is opening to a position and uses too much current to achieve that position, the diagnostic will fail. Also at every key on, the egr valve tries to recalibrate it’s position. Flash is available as a technical service buliten at the dealership if not already updated
