After driving for a long time, there will naturally be some small problems, and some car owners may immediately run to the repair shop for repairs. In fact, some car failures are only minor problems, and they can be solved by themselves, without having to run to the repair shop to spend unnecessary money. For example, today's today, the car has been driving for a long time, the fuel consumption has suddenly increased, don't worry, as long as you change these 3 parts, the fuel consumption will immediately drop.
Lambda sensor
If the fuel consumption is not increased due to poor use of the car, you may wish to check the oxygen sensor. Damage to the oxygen sensor in the exhaust pipe will lead to incorrect feedback information on the exhaust gas of the car, such as feedback that the car fuel is insufficient, the output power is insufficient and other error information, resulting in the wrong collection of information by the car computer, which in turn increases the amount of fuel injection and increases fuel consumption. If you find that the problem is the oxygen sensor, you can clean it or directly replace the new oxygen sensor.
spark plug
Generally, when the car travels about 50,000 kilometers, the spark plug is almost replaced, because it is already very seriously aged. The aging of the spark plug will lead to weak ignition and insufficient power supply, so in order to provide more power, it is necessary to consume more raw materials, and fuel consumption will definitely increase. In this case, as long as the new spark plug is replaced, the fuel consumption of the car will be significantly improved.
Activated tank carbon
If there is no problem after the above two places are inspected, you can check the fault of the activated tank carbon solenoid valve. The role of activated tank carbon is to absorb gasoline steam, and secondary utilization, if the activated tank carbon solenoid valve fails, the engine power will be greatly reduced, fuel consumption will also be greatly increased. If there is a problem in this regard, you can go to the repair shop to replace the activated tank carbon, and the fuel consumption can be improved.
