The EGR valve recirculates a portion of exhaust gases back into the intake to reduce combustion temperatures and lower harmful NOx emissions. Signs of failure include: a check engine light with an EGR code, rough idle caused by a stuck-open valve introducing too much exhaust gas, a hesitation during acceleration, or increased emissions at an emissions test. Replace a faulty EGR valve to restore proper emissions control and smooth engine operation.
