EGR Valve and Sensor Assembly
The EGR valve is mounted to the intake manifold under the carburetor. The valve controls EGR flow through a pintle valve and seat. An EGR valve position sensor (EVP) is attached to the valve and provides an electrical signal to the ECA indicating EGR valve position. The EGR valve, unlike standard EGR valves, has no opening to observe pintle valve movement. The EGR valve and position sensor are serviced as individual units.
