What are the symptoms of a faulty idle barometric pressure sensor in the Wuling Zhiguang?
1 Answers
When the vehicle's barometric pressure sensor is damaged, it is prone to issues such as easy stalling, stalling during neutral coasting, and unstable idle speed. Below is a related introduction to the barometric pressure sensor: 1. Function: The intake pressure sensor monitors the intake pressure, which is then calculated by the computer to indirectly measure the intake air volume, controlling the fuel injection time of the injector. It also serves as the engine load signal, controlling ignition timing and idle stability. 2. Working Principle: The thin film surface in the structure of the barometric pressure sensor forms semiconductor deformation pressure. External force (pressure) causes the thin film to deform, producing a piezoresistive impedance effect, thereby converting the change in impedance into an electrical signal.
