What is the issue with the Tuya Nuo SVS light?

The Tuya Nuo SVS light indicates an engine fault. SVS indicator light: This is an engine fault indicator light, equivalent to the 'engine-shaped' indicator. It illuminates when the ignition key is turned on and turns off after the vehicle starts. If the engine ECU detects a fault, the SVS light will illuminate. If this light comes on while driving, it indicates an engine fault. SVS fault indicator light: This is a fault light that appears when the ECU or TCU of an electronically fuel-injected vehicle detects issues with the engine or automatic transmission. Therefore, all electronically fuel-injected vehicles have an SVS fault indicator light. For manual transmission vehicles, it indicates an engine fault, while for automatic transmission vehicles, it indicates faults in both the engine and automatic transmission.
My car is a Toyota Camry, and the SVS light came on recently, which really gave me a scare. SVS stands for Service Vehicle Soon, indicating that the vehicle needs service, usually referring to a fault or maintenance requirement. There could be many possible reasons, such as a dirty oxygen sensor, an emission system error, or an aging battery. In my case, it was carbon buildup on the sensor that caused the light to come on and the car to shake. I rushed to the 4S dealership, where they used an OBD scanner to read the fault codes, confirmed the issue, and then cleaned and replaced the necessary parts. Ignoring it could lead to engine damage or a sharp increase in fuel consumption, costing more in the long run. Now, I regularly check the electronic systems to avoid recurrence. This light is a protective reminder, and driving safety should never be taken lightly. I recommend pulling over immediately and seeking professional help without delay.
Having worked on many cars, the SVS light indicates that the vehicle requires service, commonly seen in Toyota models. Common causes include errors reported by the engine control module, a clogged catalytic converter, or minor issues like a loose fuel cap. Once, a customer's car had the light constantly on due to a loose cap, and tightening it solved the problem. Using a diagnostic tool to scan the OBD fault codes can quickly pinpoint the issue. Don't delay fixing minor problems to avoid costly major repairs. During maintenance, check sensors and airtightness to extend part lifespan and save money. Experience tells me that early resolution brings peace of mind, and a reliable car is a worry-free drive.
