Whats a EGR valve do?
Integral to the vehicle’s engine management system, the aptly named exhaust gas recirculation valve, or EGR valve for short, recirculates finely metered quantities of exhaust gas to the engine intake system for increased engine efficiency, reduced fuel consumption and lower NOx emissions.
How does the EGR valve in a Mazda Miata work?
The EGR valve in your Mazda Miata reduces the nitrogen oxide emissions produced by your engine. It significantly diminishes harmful emissions by recirculating a fraction of the exhaust back to the engine cylinders and removing combustible matter from each cylinder.
What does excessive EGR flow on a car do?
If the code is P0402, the diagnosis is excessive EGR (exhaust gas recalculation) flow. The EGR system recalculates exhaust back to the intake manifold to lower the oxygen content of the intake gases, thereby cooling the combustion chamber, which in turn lowers NOx emissions. This is done by opening and closing an EGR valve.
What causes a check engine light on a Miata?
This is done by opening and closing an EGR valve. The Miata’s computer calls for the valve to open and close based on a number of factors. If the computer senses that this is not being done properly (valve stuck open or closed or lines plugged), then the CEL is turned on.
Is it easy to remove the EGR valve?
Removing the EGR valve and cleaning it is a fairly simple and easy task, so you can perform it yourself and save the money needed for a mechanic.
