How do you inspect, test, and replace EGR Valve in the EGR system on Nissan Quest?

The EGR system works to lower down the NOx production through the circulation of some portion of the exhaust gases to the intake manifold, so as to minimize the combustion temperature. These are EGR valve, an EGR Control solenoid valve, an EGR Temperature sensor, and an EGR Control Backpressure Transducer. It is controlled by PCM; the EGR solenoid is opened through the vacuum system that is connected to the intake air after the throttle valve. The back pressure transducer, has the function of measuring the exhaust back pressure to control the EGR vacuum signal The temperature sensor has the function of updating the PCM on the changes in the EGR passageway. To do this, examine the hoses for signs of wear or improper connection, and moving the EGR valve by bringing the engine to the warm up and acting on the throttle. If the valve does not move, one should look at vacuum signal and the connection. For the component checks, apply vacuum to the EGR valve to check it opens and holds and check for deposit level to decide if cleaning is required. Thus, the solenoid has to be checked for vacuum presence and battery voltage and the leakage of the backpressure transducer. It is expected that the resistance of the temperature sensor should drop as the temperature goes up. As for replacements, one should remove the certain elements, decontaminate the skin to avoid blockage, and then install new elements properly.
