What is the sign of the car faucet?

The sign of the faucet on the dashboard of an automobile is the fault light of the automobile engine. The long light indicates that there is something wrong with the combustion state of the engine, the engine knocks, the fuel quality is poor, and the engine cylinder is not clean.

When we are driving, if the engine fault light is on, it is likely that the engine is not burning well, the engine is knocking, the fuel quality is not good, and the engine cylinder is not clean. Once the engine fault light is lit, it will not disappear automatically in most cases, and it may disappear automatically.

Extended data:

The indicator of automobile dashboard is engine fault indicator.

When the electronic control system, gas distribution system and cooling system of the engine fail or the parameters deviate from the specified values, it will light up.

Common reasons are:

1. The poor contact and damage of the oxygen sensor make the computer unable to identify the engine combustion, which leads to the failure of the automatic control function of the emission part.

2. The cam sensor and crankshaft sensor are damaged or have poor contact, which leads to inaccurate ignition time, insufficient fuel combustion and serious decline in efficiency.

3. Poor contact between throttle motor and throttle sensor, air flow sensor and absolute pressure sensor or parameter change, which leads to the computer unable to accurately judge the air supply, resulting in inaccurate fuel mixing ratio and incomplete fuel combustion.

4. The change of the resistance of the water temperature sensor leads to improper starting time of the electronic fan, which makes the working temperature of the engine deviate from the specified value, or causes poor sealing of the cylinder and pipeline after high temperature, which reduces the working efficiency of the engine.

5. The fuel contains impurities or moisture, which increases the pollutants in the cylinder, resulting in poor discharge of spark plugs, insufficient combustion and substandard exhaust.

6. The water tank leaks, which causes the temperature of all parts of the engine to rise and the sensor parameters to change everywhere.

7. Poor contact of the oil pump will lead to poor fuel injection and incomplete engine combustion.
