What is the yellow light of 07 Fit engine?

The yellow light on the engine of Pacific Auto Network indicates that there is something wrong with the engine.

The engine light on the car is yellow. The engine light on the car is yellow, indicating that there is something wrong with the engine. Generally speaking, the indicator light on the instrument cluster lights up, indicating that the components are abnormal. There are many reasons for the engine fault light to light up, which may be that the engine oxygen sensor is damaged. The driving computer will monitor the oxygen concentration in the exhaust gas according to the oxygen sensor, control the fuel injection quantity of the engine and adjust the air-fuel ratio of the engine through the information from the sensor. If the oxygen sensor is damaged, the trip computer will not be able to receive the information sent by the oxygen sensor, and the engine fault light will light up. It may also be caused by the damage of the air flow sensor. If the air flow sensor is damaged, the driving computer can't sense the intake information, and the engine fault light will naturally light up, which will also affect the normal operation of the engine. Excessive temperature of automobile engine or serious carbon deposition in engine combustion chamber may lead to engine knocking. In general, when the engine knocks, the driving computer will monitor it in time and eliminate the knocking as much as possible by delaying ignition. If the driving computer can't handle it in time or exceeds the processing capacity, the engine fault light will light up, and the engine must be repaired at the 4s shop in time.
