there are no electronic issues with the solenoid, cleaning the EGR valve is an affordable repair method with a high rate of success. 2008 F-350 Lariat Crewcab Dually 4x4 6. A Diesel Particulate Filter (DPF) has been built into your diesel engine to help remove diesel particulate matter or soot from the engine. Mainly EGR and the PCM has shut the truck down because of the missing dpf. HELP 2008 F-350 Lariat Crewcab Dually 4x4 6.4L. P0404 - Exhaust gas recirculation circuit range/performance (many possibilities, one of which is the valve position is not matching that commanded by the PCM)Īs long as the valve is mechanically stuck/sticking, i.e. Still will not start with DPF Deleted on tuner. he started running when he became a father, this guy tried steph currys nba. P0402 - Excessive EGR flow detected (valve sticking/stuck at or near the open position) EGR Temperature Sensor Outlet for 2008-2010 Ford Powerstroke 6.4L. Cooler is always better inside your engine. This exhaust mixes with the intake air and actually cools the combustion process. PTO mode and its idle speed controls trump idle up. The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. P0401 - Insufficient EGR flow detected (valve sticking/stuck at or near the closed position) Idle up will not function for the first 30 seconds after engine start on the 6.4L engine. 2012 has doesnt use DEF however it still has a DPF.
Extended periods of idling (where wet-stacking occurs) can plug the EGR valve in short order and at very low miles. My fathers 2012 is a DRW 4.10 that couldnt get 13mpg stock unless travelling below 70mph. The 6.4L Power Stroke’s dual EGR cooler and dual poppet EGR valve was definitely an improvement over the hardware used on the 6.0L, but the EGR system still only functions so long before a problem arises. EGR valve issues should trigger one of the following codes: 2012 does not use DEF, but fuel mileage in stock trim is lower than a 6.7 cummins that uses it.
This is typically accompanied by excessive black smoke exiting the tailpipe, rough idle, running rough at low RPM, and all around low power/response. An EGR valve that sticks in the open position provides maximum EGR flow into the incoming air stream. If performance tunes or other injection modifications give your truck a tendency to produce more smoke, the same soot is passing through your EGR system.Īn EGR valve that sticks in the closed position provides no EGR flow into the incoming air stream and noticeable symptoms are typically low, although this has been known to contribute to an over-boost condition. Consider this - what comes out of your tailpipe must also pass through the EGR valve. Modified engines be more susceptible to EGR valve clogging concerns due to a greater production of exhaust soot. We recommend 6.0L Power Stroke owners service their EGR valve every other oil change or once per year - this is typically routine enough to avoid complications, although some engines suffer from more persistent problems.
