Hochgeladen am 17.01.2012OBDII Trouble code P0401 is an EGR code. More specifically it is insufficient flow. In this case the computer does not detect enough EGR flow. Exhaust Gas Recirculation. If you take a systematic approach you can quickly identify the problem. The first thing I always do is verify that the EGR is capable of working. On vacuum controlled valves it is as simple as applying vacuum to the valve at idle. If the engine stumbles or dies then you know the EGR is capable of working. If nothing happens then you either have a defective valve or the passages are clogged by carbon deposits. This is a very common problem. If the engine does stumble or die then you have another problem. Either the computer cannot control the EGR, possibly a defective vacuum switching valve, or a vacuum hose is split or somehow leaking vacuum, or the valve is working but the computer does not detect it is working. In that case you possibly have a defective lift sensor, or EGR temp sensor. Or you could have a wiring problem or loose ground. The list goes

P0402 Code

means that there is not enough exhaust gasses flowing back into the incoming air to p0401 vw the engine. EGR stands for "exhaust gas recirculation". The EGR system consist of three parts: EGR valve, DPFE (differential pressure sensor EGR) p0401 ford expedition and actuator solenoid.Car manufacturers created this system so already burned exhaust gas can flow back into the engine (when the EGR valve is open) and lower the combustion temperatures. This helps reduce emissions.This OBD code basically https://www.youtube.com/watch?v=Q_YpD0Og-4c means that the cars computer has tried to open the EGR valve, but it cannot get enough exhaust gas into the engine. EGR systems used to be controlled by engine vacuum via hoses and valves. Now most of them are controlled by electrical solenoids. What Causes the P0401 Code?

For this I personally use and recommend ALLDATAdiy. With full manuals for over 30,000 vehicles online, you will find an exact match for your vehicle's year, make and model.Besides being cheaper than a factory manual, they also offer step by step repair instructions and detailed diagrams beyond what is found in most printed manuals. Click here for a sample of their diagnostic and repair information. How to Fix Engine Code P0401 Each car manufacturer has their own EGR system design but the most likely two causes of this code are the valve itself or passageways (many times the intake manifold will have very small passageways that get clogged with soot) that the exhaust gasses pass through.Many times this code is caused by clogged EGR passages, and sometimes removing the sensor will give you access to the clogged EGR passages.Another thing that you can do yourself is to check all vacuum hoses and all wiring going to the EGR valve. You might find a hose with a hole in it or you could find a connector that is not seated all the way or some wiring that has been rubbed through.This fault code is a tougher one fo

ready to drive your car off of a cliff.  What does this P0401 diagnostic trouble code mean anyway?  The correct definition for this diagnostic trouble code P0401 is "Insufficient EGR Flow Detected".  YES.. your http://www.engine-misfire.com/p0401/ EGR valve could be bad causing this code.  But chances are there is going to be something more causing your computer to flag this p0401 code.  In this article, we are going to explore a few different possibilities that can cause this code as well as testing strategies to be able to diagnose and fix this P0401 code once and for all. EGR valve stands for Exhaust Gas recirculation.  The Exhaust gas recirculation valve takes p0401 code exhaust gases from the exhaust manifold and puts them back into the intake chamber where they get sucked back into the engine and goes through the burning process for a second time.   Because the exhaust gases have a significant amount less oxygen then the atmospheric air coming into the engine, this will cool the burning process down resulting in lower emissions (NOX) coming out of the tail pipe.  The computer will flag your P0401 error code p401 code in the computer when it recognizes that there is not enough exhaust gas going back through the intake chamber… or simply, low flow which causes the computer to flag the P0401 code. How does your computer know how much exhaust gas is being burned if any?  Different manufactures do it differently.  Some manufactures use the oxygen sensor to monitor the oxygen (air fuel) ratio in the exhaust as the engine is running.  The computer will watch the o2 sensor signal as it commands the EGR valve open.  If it does not see the right change in the o2 sensor signal, it will flag your P0401 code.  Other manufactures use the MAP sensor.  When the EGR valve is commanded open by the computer, the manifold vacuum will change and MAP sensor signal will change.  In addition, some manufactures (like Ford) use an EGR sensor or a DPFE sensor to tell the computer where the EGR valve is positioned or how much flow the EGR is currently flowing at any given time.  The EGR valve position sensor is located right on the EGR valve itself while the DPFE sensor (Digital Pressure Feedback EGR) is separate from the EGR valve.  It uses two hoses attached to the exhaust or exhaust manifold.  It senses the pressure difference (hence Digital Pressure Feedback) between the two ho
