How do you replace the egr valve on a 1995 Toyota Avalon?

Answer 1

i just did one today, the best way is to remove the airbox and conduit to the throttle body, remove the 3 plugs connected to the throttle body, remove the 2 nuts and 2 bolts from the throttle body. there is a plug bracket connected to the lower left stud, this is for the egr temp sensor, disconnect it. now slide the throttle body off the studs about an inch or so so the egr can slide out. remove all the nuts from the valve including the two accessed from behind the intake (these are a little tricky, it helps to remove the 12mm bolt on the bracket that holds the intake plenum up and slide the bracket toward the drivers side) remove the modulator assy with its bracket (its got a short hose on it that attaches to the stainless tube on the egr valve) with all that out of the way you can pull the old valve out. replacement is reverse of removal.
