What is the yellow light of BYD Song pro oil meter?

The yellow light on the fuel gauge is only a warning, because the product designer has designed such a warning light considering that some people don't look at the fuel gauge when driving, and the cruising range of 50 kilometers after the fuel gauge is lit can also meet the needs of finding a gas station.

1. Exhaust emission is not up to standard: for example, poor fuel, failure of three-way catalyst, excessive carbon deposition in intake pipe, blocked fuel nozzle, failure of oxygen sensor, and occasional engine flameout. Basically, it will affect the lighting of engine fault lights, among which the oil quality difference has the greatest influence on the lighting of engine fault lights; Just replace the three-way catalytic converter;

2. The lighting of the fault lights affected by the poor working of the engine system, such as the fault of the accelerator pedal sensor, accelerator position sensor, air flow meter and crankshaft position sensor or poor line contact, will basically affect the lighting of the engine fault lights; Need to replace related sensors or lines;

3. Some vehicle transmission system faults are also indicated by engine fault lights, such as internal transmission faults, slippage, high temperature, etc. Need to go to the repair shop for repair inspection.
