Teach you how to judge the quality of a car oxygen sensor by observation.

Today we will talk about the car oxygen sensor, I believe that there are still many friends who do not know much about the oxygen sensor, and do not know how to judge the quality of the oxygen sensor, so let's teach you how to judge the quality of the oxygen sensor by color.

We can judge the quality of the oxygen sensor by observing the color of the top part of the oxygen sensor:

1. Light gray top: It is the normal color of the oxygen sensor

2. White top: contaminated by silica gel, the oxygen sensor must be replaced at this time.

3, brown top: contaminated by lead, if the pollution is more serious, the oxygen sensor must also be replaced.

4. Black top: caused by carbon deposits, after eliminating the fault of carbon deposits in the engine, carbon deposits on the oxygen sensor can generally be automatically removed.

The existence of car oxygen sensors can not be underestimated! Once the car oxygen sensor fails, the computer of the electronic fuel injection system cannot accurately obtain the information of oxygen concentration in the exhaust pipe, and then cannot feedback control the air-fuel ratio. After a long time, the car is prone to failure problems such as engine idling instability and lack of fire. Once the car oxygen sensor fails, it must be repaired or replaced in time!
