There isn't an egr valve on an 02 Trans Am. The engine received upgrades from the Corvette that year that allowed for the egr valve to be deleted from the design.
Right on top of the valve cover
Inside the trans pan.
It is located on the drivers side of the engine right next to the crank case..........and I think that you mean EGR valve.
Where is the ERG valve located on a Chevy Vandura 5.7 350 engine?
An ERG is a unit of work. An EGR is a valve that usually sits on the manifold and is controlled by a vacuum diaphram.
It is in the trans, on the valve body.
That is part of the trans range sensor (trs) inside the trans on the valve body.
The EGR Valve its self is around 77 dollars and the gasket is about 2.50 so if you do it yourself it will be 79.50 taking it in could cost 100+
The ERG valve on a 1999 Chevy Express van is near the carburetor. It is bolted on the intake manifold.
It is inside the trans, on top of the valve body.
If your EGR valve is vacuum operated, simply remove the vacuum hose from the valve.
I changed erg valve o2 sensor and gas cap but lights back on what do I do
