How Does the Exhaust Gas Recirculation System Work and How Do You Test and Replace EGR Valve on Pontiac Fiero?

One of the major emissions control strategies is the Exhaust Gas Recirculation (EGR) system which is to reduce NOX emissions through reduced combustion temperatures through the EGR valve recirculates exhaust gas to combustion chamber. The EGR valve depends on either ported or full manifold vacuum and opens during warm engine operation and engine idle speed and above, and with changes in vacuum and back-pressure on the exhaust determines the amount of recirculating gas. There are three types of EGR valves: positive backpressure, negative backpressure, ported vacuum-all are different and regulated in various ways. The positive backpressure valve includes a vacuum Bleed and the negative backpressure valve varies exhaust gas flow depending on the manifold vacuum and the backpressure of the exhaust system. This valve is ported directly to the throttle so that its operation of recirculation depends on the opening of the throttle. In the case of ECM controlled valves, there is a diaphragm which provides the means by which the exhaust gases are drawn into the intake manifold, while there is a vacuum solenoid that uses pulse width modulations to control the of the recirculation of gases. Every EGR valve is assigned a serial number which is imprinted on the valve body to show what type of valve it is. Regarding non-ECM-controlled valves check for looseness, pressure, and vacuum signals, and check movement of the diaphragm. In the tests done for ECM-controlled valves, solenoid vacuum harness is disconnected and movement of the valve is witnessed under different circumstances. Some of the components require the disconnection of the hoses, the removal of the valve and there has to be adequate cleaning of the valve and passages to avoid the buildup of deposits that hampers the working of the component. Lastly the new components the torque specification and the connectivity between components have to be strictly followed.

Pontiac EGR Valve removes unfriendly nitrogen oxides that are recycled through the combustion loop. In 1926, Pontiac began to head turn and soon began establishing an appropriate road reputation by combining high profile stance with aggressive lines that allowed normal drivers to feel firmly rooted and bold on both curves and straightways. Pontiac ensured the edge as long as thrill was involved by hurling muscular bodies on top of spirited chassis, allowing movers such as Firebird and Grand Am to provide to anybody who was willing to push throttle and steering wheel to the limit. Cabins were also treated as command centers with the company cutting weight where necessary but loading the cabin with gauges and controls that communicate directly, hence teenagers and veterans know what the car wants when at any given speed. Pontiac had never ceased changing style, bending sheet metal to make it have a wider grip and punching hood scoops to look attitudinal and keeping the electronics always up to date so drivers could remain connected without losing the raw mechanical feel that made the badge fun. These engines have EGR Valve that directs a controlled flow of exhaust gas into fresh intake charge that reduces the combustion temperature, reduces the production of nitrogen oxides, ensures that idle is smooth, and the spark curve remains aggressive without knocking. The EGR Valve is now responsive to load and speed, opening further when in light cruise and closing further in hard accelerations, thus power remains sharp when you need it and emissions remain low when you glide. EGR Valve will remain steady when the owners run hot exhaust through it frequently, and carbon accumulates, creating a rough idle and stalling to occur when running city routes. Periodic cleaning of passages will maintain passages open.

The EGR valve depends on either ported or full manifold vacuum and opens during warm engine operation and engine idle speed and above, and with changes in vacuum and back-pressure on the exhaust determines the amount of recirculating gas.

This valve is ported directly to the throttle so that its operation of recirculation depends on the opening of the throttle.

Regarding non-ECM-controlled valves check for looseness, pressure, and vacuum signals, and check movement of the diaphragm. In the tests done for ECM-controlled valves, solenoid vacuum harness is disconnected and movement of the valve is witnessed under different circumstances. Some of the components require the disconnection of the hoses, the removal of the valve and there has to be adequate cleaning of the valve and passages to avoid the buildup of deposits that hampers the working of the component. Lastly the new components the torque specification and the connectivity between components have to be strictly followed.
