Hello,

EGR stands for Exhaust Gas Recirculation. It is a process where under the right conditions the PCM AKA, "computer" decides to divert some of the engine exhaust back into the throttle body. It is then mixed with incoming air/fuel charge and reburned, to get any harmful pollutants burned out. As for your your vehicle it does not have an EGR system. Instead the computer precisely controls the amount of fuel your engine burns, thus, leaving no need for an EGR system. I have included some supporting documentation in the diagrams below.

Thanks,
Alex
