EGR valves control the amount of oxygen that enters the combustion process in an engine. If there is too much oxygen and the fuel level is reduced to an economical level, the combustion temperatures become so high that pistons and exhaust valves burn and/or melt, and exhaust manifolds will literally glow red. By carefully controlling the amount of oxygen in the mixture, engineers have discovered a way to reduce the fuel consumption while maintaining an acceptable power level. EGR is an acronym for "Exhaust Gas Recycling", which means that a controlled percentage of combustion gas is allowed back into the engine to lower the percentage of oxygen. A faulty EGR valve can cause too much of the exhaust gas into the engine or worse, not enough. If it's not enough, your engine can literally burn itself to the point that it is useless. It's important to keep your EGR valve operating properly. Placement of the EGR valve is different on the different engine configurations. You'll need to take a look at the replacment EGR valve and look around for yours, or even ask the sales clerk.

Where is the ERG valve located on a Chevy Vandura 5.7 350 engine?
That's EGR valve, not ERG, and it stands for Exhaust Gas Recirculator, which is not exclusive to the Ranger by any means. All modern cars have them. Exhaust gases are sent back into the intake to burn-off remaining unburnt gases.
The EGR valve for the 4.0 L OHV V6 engine is located on the driver's side of the engine - Helpfull
I have not heard of such. There is an ERG valve and sensors for oil and smog but not just for position.
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.

The ERG valve on a 1999 Chevy Express van is near the carburetor. It is bolted on the intake manifold.
take off the plastic engine cover by removing the 4 bolts. the ERG valve will then be accessible. it is on the driver's side between the engine and the battery.
Right on top of the valve cover
This might depend on the year, but mine is located on the drivers side of the throttle body.
