Why is the engine fault light of the Envision always on?

[VonArya]

There are many reasons why the engine fault light of the Envision is on. The details are as follows: 1. Insufficient engine oil: When the engine oil is insufficient, the cylinders and pistons cannot be lubricated, which affects their normal operation and triggers the engine fault light. Solution: In this case, the engine oil needs to be replenished immediately. Additionally, the engine oil and oil filter should be replaced every 5,000-8,000 kilometers. 2. Overheating engine: After prolonged aggressive driving, the engine temperature may rise excessively, causing it to operate under overload and triggering the engine fault light. Solution: In this case, turn off the engine and wait for it to cool down to normal levels. 3. Engine misfire: An engine misfire prevents the engine from operating normally. In this case, a thorough inspection and repair at a repair shop or 4S store is required.
