What is the SVS warning light?
1 Answers
SVS is the engine malfunction indicator light. Below are the specific reasons why the engine warning light may illuminate: 1. Poor combustion: Suboptimal engine combustion is the primary cause of the engine warning light activation. To ensure the engine operates in good condition and maintains normal service life, oxygen sensors are installed to monitor combustion status. If combustion quality deteriorates—such as excessive hydrocarbon gas, carbon monoxide, or nitrogen oxide levels—it not only pollutes the environment but also leads to fuel waste and excessive engine wear. 2. Engine knocking: The engine is equipped with a dedicated knock sensor to monitor knocking. Engine knocking indicates potential severe mechanical damage or significant power loss. Typically, knocking is categorized as detectable or undetectable. In cases of undetectable knocking, the engine control unit adjusts parameters to mitigate adverse effects. However, when undetectable knocking exceeds the control unit's adjustment capacity, the engine warning light will illuminate as an alert.
