What is the reason for the fault light of Land Rover Range Rover engine?

Generally speaking, the fault light of Land Rover Range Rover is on, which may be due to carbon deposition on the accelerator, which makes it difficult to start the vehicle and the fault light is on. If the air-fuel ratio exceeds the standard range, the fault light will also light up. It is recommended that you go to the dealer to check the engine data and confirm whether it is necessary to clean the fuel system.

The possible causes of engine fault lights can be roughly divided into the following three categories:

1, false fault. The fault code is reported, but it works normally. It may be that an operation is beyond the control of the computer. You can eliminate the fault codes fed back by the computer first, and then see if the fault codes are still skipped.

2, minor problems. There is no obvious fault with the engine. According to the computer detection information and further inspection, it is found that there is a certain fault, which does not affect the normal driving or has little impact, and needs to be found and solved in time. For example, the intake pressure sensor is faulty.

3. Major failure. This kind of fault can be felt by naked eyes and driving experience, and it seriously affects the normal work of the engine and needs immediate maintenance. For example, the engine is obviously underpowered, which is probably a problem with the oxygen sensor.
