What is the reason why Buick Regal engine fault light keeps on?

The sensors mentioned here include water temperature, crankshaft position, air flow, intake air temperature, oxygen sensor, etc. When these sensors are damaged, the contact is poor or the signal is interrupted, the ECU of the automobile can't get the engine data accurately, which will lead to the engine fault light.

Solution: Repair the sensor.

2. Maintenance issues

Improper engine maintenance is the most common cause of engine failure. We know that all vehicles have a certain maintenance period. If the owner fails to maintain them on schedule, coupled with bad driving habits, it will increase the burden of engine operation.

Matters needing attention in engine maintenance

Clean air filter

The air filter is directly related to the air intake of the engine when the car is running. The manager of Guangben dealership told the reporter that the air filter will not be blocked when the car is only driving in the urban area, but if the car is driving on dusty roads, it is necessary to pay special attention to the cleanliness of the air filter.

If the air filter is blocked or there is too much dust, the air inlet of the engine will be blocked, and a large amount of dust will enter the cylinder, which will accelerate the carbon deposition speed of the cylinder, which will hinder the ignition of the engine and cause insufficient power, and the fuel consumption of the vehicle will naturally increase.

If you drive on a normal city road, you should check the air filter when the car travels 5000 kilometers. If there is too much dust on the filter element, consider using compressed air to blow out the dust inside the filter element. But the pressure of compressed air should not be too high to avoid damaging the filter paper.

Remove throttle sludge

There are many reasons for fouling at the throttle, some of which are carbon deposits formed by the exhaust gas from fuel combustion at the throttle; Then, impurities that are not filtered by the air cleaner will remain on the throttle. Too much sludge will cause air resistance and increase fuel consumption.
