Why is the Sagitar malfunction indicator light on?
2 Answers
The reasons for the Sagitar malfunction indicator light being on are as follows: Failure to maintain the car in time: The vehicle has a certain maintenance cycle. If not maintained on schedule, coupled with poor driving habits, it will increase the burden on the engine operation, causing the engine malfunction indicator light to turn on. Car self-check: This is the car's self-check behavior, which means the car automatically checks whether there are any problems with each module after ignition. If there are no problems, the malfunction indicator light will automatically turn off. This is a normal phenomenon. Sensor damage: Including water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, have poor contact, or signal interruption, the car's ECU cannot accurately obtain the engine data, which will cause the engine malfunction indicator light to turn on.
That day when I was driving my Sagitar on the road, a small yellow light suddenly popped up on the dashboard, and my heart skipped a beat. It was most likely an engine management system alert, common issues like abnormal oxygen sensor readings, clogged catalytic converter, or aging spark plugs causing misfires. I casually checked if the fuel cap was tightened and found it was loose by half a turn. After tightening it, the light actually went off. If that hadn't worked, it would've been best to quickly find a repair shop to connect an OBD scanner and check the fault codes. A yellow light means you can still drive slowly to get it fixed, but don't delay until it turns red—that would be trouble. Also, pay attention to any unusual engine noises and check if the exhaust smells pungent; these details can help the technician locate the fault faster.
