What does 'sys' mean on the car dashboard?

[MacElena]

The 'sys' on the car dashboard is an abbreviation for the English word 'system', indicating a general engine system malfunction. This symbol corresponds to dozens of minor engine faults, and the specific issue can only be identified by reading the fault code with a computer. It is usually caused by abnormal intake or ignition. Reasons and solutions for abnormal car intake or ignition: Clogged air filter: If the air filter is clogged or has excessive dust accumulation, it will hinder engine air intake. A large amount of dust entering the cylinders will accelerate carbon buildup, causing poor engine ignition, insufficient power, and naturally increasing the vehicle's fuel consumption. In this case, the air filter needs to be cleaned to remove dust blockages. Increased sludge: There are many reasons for sludge formation at the throttle, including carbon deposits from fuel combustion exhaust at the throttle and impurities not filtered by the air filter accumulating at the throttle to form sludge. Excessive sludge can cause air resistance during intake, leading to increased fuel consumption. In this case, it is necessary to promptly clean the car's throttle to remove carbon deposits and impurities, thereby eliminating the sludge.
