1 Answers
When the engine yellow light comes on in a new car, it indicates that there is an issue with certain components of the vehicle's engine. Here are the reasons why the engine warning light may illuminate: 1. Exhaust emissions not meeting standards: Factors such as poor fuel quality, failed catalytic converter, excessive carbon buildup in the intake manifold, clogged fuel injectors, faulty oxygen sensors, or occasional engine misfires can trigger the engine warning light. Among these, poor fuel quality is the most common cause. 2. Poor engine system performance: Issues like faulty throttle position sensors, air flow meters, crankshaft position sensors, or poor electrical connections can cause the engine warning light to illuminate. 3. Transmission system malfunction: In some vehicles, transmission system issues such as internal failures, slipping, or overheating may also be indicated by the engine warning light.
