How does the oxygen sensor affect fuel consumption, and why does fuel consumption increase when it i

The oxygen sensor mainly controls the air intake of the engine, so if it is broken, the engine will give some wrong instructions, causing an increase in fuel injection, which in turn leads to an increase in fuel consumption.

The participation of the aerobic sensor is called closed-loop control, and the open-loop control without the participation of the oxygen sensor. 2. The closed-loop control can keep the air-fuel ratio near the theoretical value, so that the gasoline can finish combustion, so the correction effect of the oxygen sensor on the fuel is very large, so the fuel consumption will increase if it is broken.

The oxygen sensor is installed on the exhaust pipe and is used to detect the oxygen content in the exhaust gas. If it is broken, the engine will keep signaling that the oxygen content is too high, then the computer will control more fuel injection, and the fuel consumption will increase.

The main function of the oxygen sensor is to detect whether the mixture in the engine is burned completely, if the oxygen sensor is broken, it is impossible to determine the combustion of the mixture, and it is impossible to transmit signals to the engine computer version, control the amount of fuel injection, so that the mixture reaches the best ratio, then the engine computer board will be adjusted to the maximum amount of fuel injection to make the engine work.

When the oxygen sensor is normal, it will not affect fuel consumption, only if it is broken and the value is inaccurate, it will affect fuel consumption. An oxygen sensor is installed on the exhaust pipe and is used to detect the oxygen content in the exhaust gas to determine the combustion status and then correct the amount of fuel injected. Therefore, if the oxygen sensor is broken, it will have an impact on the combustion state, emissions, and fuel consumption.

Hello! Yes! The function of the oxygen sensor is to detect the concentration of the mixture of exhaust gas, if the oxygen sensor is broken, the concentration of the mixture cannot be detected, and the computer will let the fuel injector inject more fuel.

The car only has one oxygen sensor, and a malfunctioning oxygen sensor will cause wrong data to the on-board computer. These incorrect figures can cause all sorts of undesirable engine symptoms, and increased fuel consumption is just one of the possible symptoms.

Oxygen sensor is an indispensable component installed on the exhaust pipe of the car, from the installation location and name we can know that the main function of the oxygen sensor is to obtain the relevant data of oxygen concentration in the exhaust of the car, and feed these data back to the brain-on-board computer (ECU) of the vehicle.

How many kilometers does the engine oxygen sensor have to be replaced?

Damage to the rear oxygen sensor does not affect fuel consumption.

The rear oxygen sensor is mainly used to monitor the working condition of the TWC.

Control of emissions, but damage to the front oxygen sensor will affect fuel consumption.

Because the pulse width of the injection mainly depends on the signal of the pre-oxygen!

The rear oxygen sensor does not affect fuel consumption, but it is impossible to determine whether the three-way catalysis is working properly and has an impact on environmental protection.
