The exhaust gas recirculation (EGR) valve on the Toyota engine, located in the back of the engine, mounts above the intake manifold on the driver’s side of the engine compartment. The valve consists of a metal cylinder that sits on the top of the engine near the firewall. The EGR valve recycles the burned emission fumes and sends them through the engine burn off a second time, reducing the amount of pollutants sent out the exhaust pipe.
Things You’ll Need: Socket wrench set
- Disconnect the exhaust pipe from the Toyota EGR valve: Using a socket wrench, remove the bolts that secure the valve to the pipe. Remove the gaskets from the exhaust pipe by hand.
