The EGR (Exhaust Gas Recirculation) valve on a Chevy Impala is located on the driver’s side of the engine bay towards the rear, regardless of whether the vehicle is equipped with the 3.4 or the 3.8-liter engine. It is important to note that starting from 2006, Impalas do not have a separate EGR valve. Instead, they use variable valve timing, which serves the same purpose as an EGR valve with additional benefits .

Can I still drive my car with a bad EGR valve?
Technically you can drive without a working EGR valve.
The role of your EGR valve is to reduce the number of toxic NOx gases in the air, so if it isn’t working quite right, more toxic gases will be released into the air. For this reason, we don’t recommend driving without a working EGR valve for too long.
