What is the issue when the Sagitar's engine yellow light comes on?

[DiMalachi]

When the engine fault light on the dashboard comes on, you can try starting and turning off the vehicle three times in a row, or disconnect the negative terminal of the engine battery, wait for 30 seconds, reconnect it, and then attempt to start the vehicle. If the engine fault light on the dashboard remains illuminated, it cannot be manually reset; you must visit a 4S shop to use a fault diagnostic tool for troubleshooting before it can be cleared. Below are the reasons why the engine yellow light may come on: 1. Sensor issues: The sensors mentioned here include the water temperature sensor, crankshaft position sensor, air flow sensor, intake temperature sensor, oxygen sensor, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which can cause the engine fault light to come on. 2. Maintenance issues: Poor engine maintenance is the most common reason for the engine fault light to illuminate. Vehicles have specific maintenance cycles, and if maintenance is not performed on schedule, combined with poor driving habits, it can increase the operational burden on the engine.
