What happens if the oxygen sensor of a natural gas car is broken

There are 2 oxygen sensors, one before and one behind, and after the front oxygen sensor fails, the accurate oxygen concentration cannot be read. Naturally, it is impossible to accurately stabilize the air-fuel ratio. The air-fuel ratio is out of tune, and of course the engine cannot function properly.

There will be an impact. If the latter one is broken, whether your three-way catalytic converter is good or bad, the car can't tell.

Hello, a broken sensor will only lead to heavy exhaust gases.

If the oxygen sensor is broken, it can't be turned on, it can't be gased, and it's as slow as walking.

Summary. When the front oxygen sensor fails, the ECU can not get the information of the oxygen concentration in the exhaust pipe, so it can not feedback and control the concentration of the mixture, (whether the fuel injection and air intake are more or less, the ECU does not know at all) so that the engine fuel consumption and exhaust pollution increase, and the engine will have unstable idling, lack of fire, surge and other fault phenomena.

When the oxygen sensor fails, the ECU can not get the information of the oxygen concentration in the exhaust pipe, and the concentration of the mixture can not be fed back and controlled because of which delay, (more fuel injection and air intake or less calming core, ECU does not know at all) so that the engine fuel consumption and exhaust pollution increase, and the engine will have unstable idling, lack of fire, surge and other fault phenomena.

Hello, the exhaust temperature sensor of the natural gas vehicle is broken, will it affect the power?

The function of the rear oxygen sensor is mainly to check the purification effect of the three-way catalysis, that is, to detect the content of the return to the denier oxygen in the waste and chaos after purification, and feed it back to the ECU, and the computer will compare the data given by the pre-oxygen, if the data given by the pre-oxygen and the post-oxygen are the same (generally the pre-oxygen signal is greater than the post-oxygen), then the three-way catalytic failure can be judged.

The pre-oxygen is bad, and it will affect

The engine sounds normal, but the power is reduced.

It definitely has an impact

Is it a big impact. It will slowly lead to the engine not working properly, and the impact will be bigger and bigger.

So replace it in time.

Okay, thank you.

You're welcome, be satisfied, and give it a thumbs up

Summary. The most common failure of an oxygen sensor is failure, and there are two main reasons for this:

The first is clogged with carbon particles, at which point the signal voltage of the oxygen sensor will be too high, and the engine computer will therefore issue instructions to reduce the amount of fuel injected, making the mixture too thin.

The second is that dust and oil block the through hole between the oxygen sensor and the atmosphere, at this time, the signal voltage of the oxygen sensor will be low, and the engine voltage will indicate that the injector will inject more fuel, causing the mixture to be too thick.

What are the symptoms of a broken oxygen sensor in a natural gas car.

The most common fault of the oxygen sensor is failure, and there are two main reasons: the first is blocked by carbon particles, at this time, the signal voltage of the oxygen sensor will be high, and the engine computer will therefore issue instructions to reduce the amount of fuel injection, so that the mixture is too thin, and the second is that dust and oil block the through hole of the oxygen sensor and the atmosphere, at this time, the signal voltage of the oxygen sensor will be low, and the motor voltage will indicate that the laughing injector will inject more fuel, causing the mixture to be too thick.

The oxygen sensor is an important part of the early stage of the electronically controlled fuel injection engine, and once the Shiyou fails, it will not only exceed the emission standard, but also deteriorate the working condition of the engine.

I hope I can help you with my balance, and I hope you can give me a thumbs up, your evaluation is very important to me, thank you, I wish you a happy life, a lot of money, and good luck. 

The impact is as follows: the oxygen sensor of a gasoline vehicle is broken, and it will cost fuel to drive.
