What is the purpose of the EGR valve on a Ford Focus?
What is the purpose of the EGR valve on a Ford Focus?
Ford Focus 1.6 TDCI – Blanking EGR valve and fault codes – Railroad. The purpose of the EGR system is to reduce NOx emissions, nothing else. The ECM knows whether or not the EGR valve is open by monitoring air flow via the MAF sensor.
How to remove and inspect EGR valve Ford Duratec HE?
Simple DIY how to: Remove, inspect, and replace the EGR (exhaust gas recirculation) valve on a Ford Duratec HE or Mazda LF engine. EGR valves get dirty over time along with the rest of the intake and exhaust components, and it’s good practice to service them by just cleaning from time to time.
Why does the fuel management light stay on when the EGR is open?
This means the amount of hydrocarbon gases emitted from the tailpipe increases significantly producing a fuel smell. Your engine management light may stay on once your car detects an issue with the EGR valve. This could be caused when the EGR is either constantly closed or open.
How is the EGR valve controlled in a car?
It is a straightforward system which utilises a vacuum to switch the EGR valve from closed to open. The vacuum is often regulated by a computer-controlled solenoid. Most modern cars utilise an electronically controlled EGR which is controlled by the vehicle’s engine control module (ECM).
Why is the Ford dpfe sensor and EGR system important?
To do that, they have developed exhaust gas re-circulation (EGR) valves and sensors to detect how well the EGR valve is working. The sensing portion of the system is important because the exhaust contains soot, and that soot can clog up the metering portion of the EGR valve.
What are the components of the Ford EGR system?
The Ford EGR system uses 3 components: • an EGR valve that opens and closes a passage from the exhaust to the intake manifold, • an Electronic Vacuum Regulator (EVR) that opens and closes passages from the intake manifold to the diaphragm of the EGR valve, and.
When to test the Ford EGR valve solenoid?
The following are the most common symptoms that a Ford (or Mercury or Lincoln) car or truck will usually experience when there’s a fault in the EGR System: Car or truck runs fine, but the check engine light (CEL) is on with an EGR Valve Fault Code: P0401 EGR System Flow Insufficient. P01406 EGR Valve Pintle Position.
What are the symptoms of a Ford EGR fault?
The following are the most common symptoms that a Ford (or Mercury or Lincoln) car or truck will usually experience when there’s a fault in the EGR system: P0401 EGR System Flow Insufficient. P01406 EGR Valve Pintle Position. Rough Idle. Really bad gas mileage.

Is there a fault code for Ford Focus 1.6?
Ford Focus 1.6 TDCI – Blanking EGR valve and fault codes – Railroad. You should also be aware that it is an offence to modify a vehicle in such a way so that it no longer complies with the emission standards it was originally designed to meet. Thanks for all the info, very much appreciated.
Why is there an EGR code on my Ford?
However, we often find EGR codes on Ford products caused by inexpensive plastic parts that falsely report position to the control module. Several technical service bulletins for a wide variety of different makes and models have documented different problems associated with the EGR valve system.
What should I do if my EGR light is not working?
The repair of this condition is removal of the EGR valve and inspection of the passageway to check for a blockage. Each model vehicle has different procedures for clearing the passageway due to many different configurations of the system. Some Fords have a removable tube.
Is the Check Engine Light ( CEL ) an EGR valve?
You tried to ignore it, but there’s just no turning your back on the fact that your Check Engine Light (CEL) is staring you in the face, threatening to fail your car at its next emissions inspection appointment. You take your car to the repair shop for some professional analysis, and they tell you that you are going to need a new EGR valve.
What does the EGR error code p0401 mean?
In the shop’s defense, replacing your EGR valve probably would eliminate the error code, turn off the CEL, and allow you to pass emissions inspection. One thing is certain: the P0401 error code specifically means you have “reduced flow” in your exhaust gas recirculation system.
