The EGR (Exhaust Gas Recirculation) valve on a Lexus RX450h is located in the engine compartment, underneath the hood. It is responsible for recirculating a portion of the exhaust gases back into the intake manifold, where they can be burned again, reducing emissions. The EGR valve is an important component for meeting emissions standards, and if it goes bad, the car may not pass emissions tests.
