What is the function of an oxygen sensor?
1 Answers
Automotive oxygen sensors are critical feedback sensors in electronically fuel-injected engine control systems. They are key components for controlling vehicle exhaust emissions, reducing environmental pollution caused by automobiles, and improving the fuel combustion quality of car engines. Oxygen sensors are installed on the engine exhaust pipe. The following are the impacts of oxygen sensor failure: 1. The computer of the electronic fuel injection system cannot obtain information about the oxygen concentration in the exhaust pipe, thus unable to perform feedback control on the air-fuel ratio. 2. It increases engine fuel consumption and exhaust pollution, leading to unstable idling, misfiring, surging, and other fault phenomena in the engine. Therefore, it is essential to promptly troubleshoot or replace the faulty sensor.
