What is the EGR code on a Mazda 6?
There are three main parts of the 6’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid. P0401 is a general code, which means that regardless of the year (1996+ anyway) and the model, it’ll have the same meaning regardless of which manufacturer built the vehicle (Mazda 6 or not).
What are the parts of the EGR system?
The EGR system on a vehicle is responsible for recirculating exhaust gasses in order to lower the vehicles emissions output. There are three main parts of the 6’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid.
What happens when you have a bad EGR valve?
The engine will have a rough idle when the EGR valve is faulty because it will remain in an open or closed position. This implies that too few or too many exhaust gases are entering the chamber, and this is why the engine is idling.
Why is my EGR not working on my Acura MDX?
Vacuum Issues – The EGR valve relies on engine vacuum to operate. So, if you are encountering P0401 and other codes, the P0401 may be a symptom of larger problems. For instance, if the motor is not running well enough to create sufficient vacuum to operate the EGR valve, than P0401 will often be thrown.

When do you use an electronic EGR valve?
Electronic EGR valves are used in vehicles dated 1990 and up. The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum. The procedure to test an electronic EGR is a bit different and requires a multimeter.
Can a multimeter be used to test EGR?
The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum. The procedure to test an electronic EGR is a bit different and requires a multimeter. If you notice your vehicle running poorly, stalling or having poor gas mileage, you should test the EGR.
Is the exhaust gas recirculation valve an electronic valve?
The exhaust gas recirculation valve within your vehicle is a crucial component in reducing harmful emissions and ensuring your vehicle runs smoothly. Electronic EGR valves are used in vehicles dated 1990 and up. The vehicle computer operates the valve instead of previous years EGR valves, which are operated by the engine vacuum.
What to do if your Mazda 6 p0401 has insufficient flow?
Check the EGR Tube- It’s a good idea to check the tube going to the EGR because it’s often the cause of P0401, easy to do, fast, and replacing it is very afMazdaable. If it’s cracked, you’ll need to get a new one. If it’s clogged you can get away with cleaning it and replacing it.
