The symptoms of a faulty automotive differential pressure sensor are: 1. The engine malfunction indicator light will illuminate and limit engine torque; 2. The signals collected by the engine control unit will be erroneous, leading to inaccurate calculated air intake and causing abnormal engine operation. An automotive differential pressure sensor is used to measure the pressure difference between two points, typically measuring the pressure difference before and after a device or component. The measured pressure directly acts on the sensor's diaphragm, causing a micro-displacement proportional to the pressure, which changes the sensor's capacitance value. An integrated circuit then converts and outputs a corresponding measurement signal within the standard pressure range.

Does the Passat have a catalytic converter?

The Passat has two catalytic converters, located at the front section of the exhaust pipe under the chassis and the middle section at the lower end of the exhaust pipe. All modern vehicles are equipped with catalytic converters. Only vehicles produced in earlier years that did not meet the National II emission standards lacked catalytic converters. Composition of a catalytic converter: A catalytic converter typically consists of four parts: the shell, vibration damping layer, substrate, and catalyst coating. The shell is made of stainless steel to prevent oxidation scale from peeling off, which could clog the substrate. The vibration damping layer is composed of padding or wire mesh pads, serving to seal, insulate, and secure the substrate. To protect the substrate from damage due to vibration, thermal deformation, and other factors, the padding is made of expanded mica and aluminum silicate fibers, bonded together with adhesive. The substrate is made of honeycomb-shaped ceramic materials, though many also use metal (including stainless steel) materials. The catalyst is composed of precious metals such as platinum, rhodium, and palladium, sprayed onto the substrate to form the purifying agent.

What is the fuel tank capacity of the Mercedes-Benz e350el?

The fuel tank capacity of the Mercedes-Benz e350el plug-in hybrid is 58.28 liters. For the same car model, the fuel tank size is identical. Drivers should regularly inspect the fuel tank for any signs of compression, looseness, or deformation. Additionally, it's crucial to check if the fuel tank cap is tightly secured, as a loose cap can lead to gas leakage and potentially cause accidents. Fuel tank maintenance includes the following: Drain accumulated water and sediment from the tank, and check for oil leaks at pipe joints and switches. For fuel tank caps equipped with air and steam valves, ensure the vent holes are clear. The filter screen at the fuel filler inlet should remain intact to prevent impurities from entering the tank and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be in good condition to avoid fuel spillage while driving. To check the remaining fuel level, observe the gasoline gauge on the right side of the instrument panel, marked with E and F. When the needle is near E, it indicates low fuel, while proximity to F signifies ample fuel.
