What does it mean when the SVS light comes on in a pickup truck?

The SVS light coming on in a pickup truck indicates that the ECU or TCU of the fuel-injected vehicle has detected an issue with the engine or automatic transmission. Solution: It is necessary to promptly visit a 4S shop for inspection. More information about the SVS light in pickup trucks is as follows: 1. When the SVS indicator light comes on, it means the engine control unit has detected a problem with one of the vehicle's sensors; incorrect signal; exceeds usage standards; the SVS light will automatically illuminate when the vehicle is powered on. 2. There are many reasons for the SVS indicator light to come on, and each needs to be checked one by one: poor fuel combustion in the engine; engine knocking during operation; the vehicle is using low-quality fuel.
A few days ago when I was driving my pickup truck on mountain roads, the SVS light suddenly popped up on the dashboard, which gave me quite a scare. SVS stands for 'Service Vehicle Soon', meaning the vehicle needs immediate inspection. I quickly pulled over, turned off the engine, and called the dealership mechanic for advice. He said it was most likely an issue with the engine or electrical system - common culprits being a dirty oxygen sensor, clogged throttle body, or something minor like a loose wiring connection. My neighbor's pickup had this same warning light last time, and it turned out to be carbon buildup in the catalytic converter, costing 800 RMB to fix. Following the mechanic's suggestion, I drove carefully to the shop to read the trouble codes while also checking the spark plugs and oil level. Eventually, they found it was just a poor connection in the mass airflow sensor - reseating the connector solved the problem. You can't afford to ignore this warning light as it can cause sudden fuel consumption spikes, and in severe cases may lead to complete engine failure.
