How to clean the EGR valve in your car?
EGR valve cleaning and testing in your car DIY with Scotty Kilmer (how it works). How to test the egr for problems and how the exhaust gas recirculation (EGR) system works (Code P0400). EGR valve location, removal, inspection, test and repair.
How is exhaust gas circulated in an EGR system?
Most EGR systems have a by-pass valve integrated with the EGR cooler. When the engine is cold, the exhaust gas is circulated directly into the engine.
What’s the code for an EGR valve throw?
What code will an EGR valve throw have? The P0401 trouble code is related to your car’s exhaust gas recirculation (EGR) system, which controls an engine and reduces emissions. Suppose a computer-controlled valve gives a certain amount of gases back into your engine to be burnt with the air-fuel mixture.
How does the EGR valve position sensor work?
The position sensor of the valve is linear and provides a signal proportional to its supply voltage (usually 5V). The EGR valve position sensor signal is set to increases in the direction of the opening of the valve. The position sensor is used for three main reasons:

How is the rotation of an EGR valve controlled?
EGR valves are also actuated by stepper motors. The rotor contains a set of permanent magnets and the stator a set of electromagnets (coils with iron core) controlled by a power electronics circuit. The rotation comes from the interaction of the rotor and the magnetic field generated in the electromagents.
Where is the entry port for the EGR valve?
Clean out the entry port. The entry port is where the valve tubes connect to the engine (usually the intake manifold) while the EGR valve is off. Reinstall the EGR valve.
