EGR is "exhaust gas recirculation" - part of the emission control
When combustion temperatures get too high, the nitrogen becomes
unstable and attaches to oxygen creating NOX, so the EGR valve
recirculates some exhaust gas back into the cylinders. Oddly the hot
exhaust gases actually reduce temperature because there is less fuel to
There is also a vacuum modulator right next to the EGR valve that
controls its operation based on engine vacuum.
The most common problem with EGR valves, is that carbon in the exhaust
accumulates on the pintel (?) (the part of the valve that moves) and
causes it to stick. So the most common cure for EGR valve malfunction
is simply to clean the valve.
