What does it mean when the engine warning light stays on?
2 Answers
The illuminated engine warning light indicates a fault in the engine system, signaling that the engine requires maintenance or servicing. When the engine warning light stays on, it may lead to three possible scenarios: 1. The first scenario is when the vehicle fails to start. In this case, there might be issues with the fuel pump or ignition components, and it's advisable to contact a 4S shop for assistance. 2. The second scenario is when the warning light is on, but the vehicle can still be driven normally. This could be due to a faulty sensor. While you can continue driving, it's best to drive slowly and at low speeds, and get the vehicle repaired as soon as possible. 3. The third scenario is when the engine warning light is on, the vehicle can still be driven but experiences severe shaking, lack of power during acceleration, etc. In such cases, it's recommended to call for roadside assistance immediately.
The engine warning light stays on, and I know a thing or two about this issue because I often tinker with my car. Usually, it means the vehicle's computer has detected a problem with the emission system, possibly a faulty oxygen sensor or incorrect fuel mixture ratio. This can lead to significantly increased fuel consumption, lack of power, and poor driving performance. Sometimes, it's just a loose sensor, but don’t underestimate it—delaying repairs could damage the catalytic converter, which would be expensive to fix. I recommend using an OBD scanner to check the trouble codes immediately or visiting a professional repair shop. If the light comes on while you're driving, try to maintain a steady speed and avoid aggressive driving to prevent further damage. Regular maintenance, such as cleaning the engine area, can prevent many faults—don’t wait until the light comes on to take action.
