What is the function of the EGR valve position sensor?

[Ronald]

egr valve position sensor functions: 1. The EGR valve position sensor provides the ECU with the position signal of the EGR valve. The EGR valve is a mechatronic product installed on diesel engines to control the amount of exhaust gas recirculated back to the intake system. 2. The EGR valve is usually located on the right side of the intake manifold, near the throttle body. A short metal tube connected to the exhaust manifold is attached to it near the throttle body. Its function is to control the amount of exhaust gas entering the intake manifold, allowing a certain amount of exhaust gas to flow into the intake manifold for recirculation. 3. The EGR valve directs the exhaust gas produced by engine combustion into the intake manifold to participate in combustion, thereby reducing the combustion chamber temperature, improving engine efficiency, and optimizing the combustion environment. 4. The working principle of the electronic EGR control system. During engine operation, the microprocessor determines the current operating condition of the engine based on signals from various sensors and outputs commands to control the opening or closing of the exhaust gas recirculation solenoid valve, thereby controlling the opening or closing of the exhaust gas recirculation control valve to start or stop the exhaust gas recirculation process.
