The exhaust gas recirculation valve, or EGR valve, works by ing a portion of the engine emissions back through the intake manifold, thereby lowering the final level of hazardous emissions. A car might experience trouble accelerating or stuttering with an improperly-operating EGR valve. On a 2000 Toyota Camry, most novice mechanics can clean or replace the valve in a few minutes. The instructions differ depending upon the engine size within the vehicle.
Four-Cylinder Engines
Step 1
Unplug the vacuum hose from the EGR valve, located near the center of the firewall.
Step 2
Unscrew the EGR valve mounting bolts with a socket wrench. Pull the valve from the intake manifold.
Step 3
Inspect the valve for a heavy amount of carbon deposits. Clean the valve with a small rag if necessary or replace the valve.
Step 4
Set the valve against the intake manifold, using a new gasket between the valve and the intake manifold. Install the mounting bolts with a socket wrench.
Plug the vacuum hose into the EGR valve.
V6 Engines
Step 1
Raise the front of the vehicle with a hydraulic jack. Set jack stands under the frame rails on the front of the car to secure it while changing or cleaning the EGR valve.
Step 2
Unscrew the EGR valve pipe bolts, only accessible from underneath the car, with a socket wrench. The pipe travels from the EGR valve on the side of the intake manifold to the bottom of the engine block.
Step 3
Detach the hose from the retaining clip on the side of the EGR valve, located near the center of the firewall, attached to the intake manifold.
Step 4
Disconnect the electrical connection from the EGR valve and pull the vacuum hose from the EGR valve.
Step 5
Unscrew the three EGR valve mounting bolts and pull the valve from the intake manifold.
Step 6
Inspect the valve for a heavy amount of carbon deposits. Clean the valve with a small rag if necessary or replace the valve.
Step 7
Set the valve against the intake manifold, using a new gasket between the valve and the intake manifold. Install the mounting bolts with a socket wrench.
Step 8
Connect the electrical connection to the EGR valve and push the vacuum hose onto the EGR valve.
Step 9
Attach the hose to the retaining clip on the side of the EGR valve.
Step 10
Install the EGR valve pipe bolts near the bottom of the engine block with a socket wrench.
Remove the jack stands from under the car. Lower the car with the hydraulic jack.
