What causes insufficient power when the SVS light comes on in a Jiangling vehicle?

[LeEzra]

The reasons for the SVS light coming on include poor engine combustion state, engine knocking, unclean engine cylinder interiors with accumulated carbon deposits, and the electronic control unit's inability to obtain engine data. When the SVS light comes on, the vehicle needs to be immediately taken to a repair shop for inspection and repair. The following are explanations of the SVS indicator light phenomenon: 1. Explanation one: SVS is a fault indicator light for abnormal vehicle emission systems. If there are no other abnormal phenomena while driving, it is mostly caused by poor gasoline quality. 2. Explanation two: When the SVS indicator light comes on, it indicates that the engine control unit has detected an incorrect signal from a sensor or that it has exceeded the usage standard, requiring sensor replacement. 3. Explanation three: Try starting the engine. If it fails to start, it might be due to an abnormal fuel pump that cannot supply fuel properly to the engine. If it can still start, it might be due to other sensor faults, requiring replacement of the fuel pump or sensors.
