What Causes the SVS Light to Illuminate?
1 Answers
SVS light is the engine malfunction indicator. When the SVS light illuminates, it indicates that the engine control unit has detected an erroneous signal from a sensor or that the sensor has exceeded its operational standards. Upon turning on the ignition, the SVS light will illuminate briefly for an automatic check and then turn off after a few seconds, which is normal. If the light remains on, it signifies a fault in the vehicle's electronic control system. Below are the reasons why the SVS light may illuminate: 1. Poor engine combustion state; 2. Engine knocking; 3. Poor fuel quality; 4. Dirty engine cylinders with carbon deposits; 5. The electronic control unit cannot retrieve engine data.
