Li Xia n5 accelerator pedal position sensor switch ab voltage relationship

The function of the sensor is to determine whether there is excess oxygen in the exhaust gas after engine combustion, that is, oxygen content, and convert the oxygen content into voltage signal and transmit it to the engine computer, so that the engine can realize closed-loop control with excess air coefficient as the goal; Ensure that the three-way catalytic converter has the maximum conversion efficiency for hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOX) in the exhaust gas, and convert and purify the discharged pollutants to the greatest extent.

Switch: Switch means to turn on and off. It refers to the electronic components that can open the circuit, interrupt the current or make the current flow to other circuits. The principle of the switch is that the "closing" of the contact means that the electronic contact is turned on, allowing the current to pass; "Open circuit" means that the electronic contact is not conductive and forms an open circuit, and no current is allowed to flow. Ordinary switches are widely used in South China and North China. The most common switch of Shanghai Jiafeng Electronics is an electromechanical device operated by people, including one or several electronic contacts.
