Aug 22, 2015· Exhaust Gas Recirculation (EGR) Temperature Sensor The exhaust gas recirculation (EGR) temperature sensor (Figure 4) is a thermister type sensor that monitors the temperature of the exhaust in the EGR passageway. As the EGR flow increases, the temperature increases. This process creates a change in the resistance of the sensor, which decreases ...
Exhaust gas recirculation. Exhaust gas recirculation (EGR) is a method of modifying the inlet air to reduce NOx emissions at source, an approach widely and successfully used in automotive applications. Some of the exhaust gas is cooled and cleaned before recirculation to the scavenge air side.
Oct 03, 2019· The Exhaust Gas Recirculation or EGR system is one of several vehicle emission control systems. It helps reduce the amount of the nitrogen oxides (NOx) in the exhaust gases. Nitrogen oxides are normally formed in the process of …
Oct 28, 2021· It means that the powertrain control module (PCM) perceives a high voltage signal from the exhaust gas recirculation (EGR) position sensor. The check engine code P0406 is triggered when the signal being sent back by the EGR position sensor to the PCM is higher than the specified range. The check engine light will activate as the PCM sets this code.
P0406 is a general ODB2 trouble code indicating a fault within the exhaust gas recirculation EGR circuit. This code is similar to P0400, P0401, P0402, P0403, P0404, P0405, P0407, P0408, P0409.

Exhaust Gas Recirculation (EGR) complete guide – architectures. Exhaust gas recirculation (EGR) is the most common technology to reduce nitrogen oxides (NOx) emissions on diesel internal combustion engines (ICE). EGR takes exhaust gases from the exhaust manifold and reintroduces them into the intake manifold, mixing them with fresh air.
Exhaust Gas Recirculation (EGR) is a system that allows the exhaust gases to be recirculated back into the intake manifold. This process leads to a significant reduction in nitrogen oxides (NOx) emissions because it reduces the two elements underlying its production: oxygen in excess and combustion temperature.
