Common questions

Can I pass smog with EGR not ready?

Can I pass smog with EGR not ready?

Answer: The EGR monitor can not be replaced, in that it is not a smog component. Emission monitors are internal self-tests which the Engine Control Unit performs to ensure a vehicle is not polluting and is running efficiently.

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.

What happens when an EGR valve is not working?

When your EGR valve isn’t working correctly more emissions will be emitted. As aforementioned if the valve is stuck open the temperature is lowered which prevents all the fuel from burning. This means an increased flow of unburned hydrocarbon gases coming out of the tailpipe.

What causes the engine management light to stay on?

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. However, it is worth noting that usually the EGR valve starts to degrade before it fails completely and the engine management system may not pick up on it until it actually fails.

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 are the symptoms of a bad EGR valve?

1. Engine performance issues. One of the first symptoms of a problem with the EGR valve is engine performance issues. A clogged or malfunctioning EGR valve can disrupt the vehicle’s air-fuel ratio, which can cause engine performance issues such as a reduction in power, acceleration, and even fuel efficiency.

Can a car pass a smog test with a faulty EGR valve?

The EGR valve is an important emissions component, especially for vehicles in states with strict emissions regulations. You won’t be able to pass a smog test with a faulty EGR valve.

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.

What causes a failure code on an EGR system?

Another common problem causing failure codes in this system is that the tip of the valve will become irregular shaped from carbon deposits. When this happens it no longer creates a perfect seal. This can allow exhaust gas to continue to flow when not called for by the computer. An example would be at engine idle or when the vehicle is cold.
