4.0forlife Posted November 3, 2016 Author Share Posted November 3, 2016 Is there a temp sensor that tells the ecu that the engine is cold and needs the egr to open Link to comment Share on other sites More sharing options...
cruiser54 Posted November 3, 2016 Share Posted November 3, 2016 I had it backwards. EGR opens when the solenoid has NO power. So, do you have power to the EGR solenoid? Link to comment Share on other sites More sharing options...
4.0forlife Posted November 3, 2016 Author Share Posted November 3, 2016 I believe so. If I unplug the solenoid while the trucks running it wants to stall. So it should have power Link to comment Share on other sites More sharing options...

Tex06 Posted November 6, 2016 Share Posted November 6, 2016 Before you condemn the solenoid, any idea what the voltages are supposed to be? Could be a corroded connection dropping voltage to the solenoid. Multimeter should make that a quick test at the plug.
