2004 6.0 excursion p0401
I had an issue with lots of white smoke. A p0401 code, then the smoke stopped. I removed the egr and cleaned it. All seamed good until two weeks later. Now I have smoke again. Its seems to be only after it is warm. Please help. Do I need a NEW egr valve?

- EGR passage clogged
- Faulty EGR Vacuum Modulator Valve
- Faulty EGR Valve
- Faulty EGR solenoid valve
- EGR solenoid valve harness is open or shorted
- EGR solenoid valve circuit poor electrical connection
- Dead (Weak) battery
- Faulty EGR temperature sensor and circuit
- Exhaust gas leaks
My bet is on the modulator valve..... I would replace it.....
