What does it mean when the Buick engine warning light comes on?

[RowanAnn]

Reasons for the Buick engine warning light coming on: 1. Exhaust emissions not meeting standards, such as poor fuel quality, failed catalytic converter, excessive carbon buildup in the intake manifold, or clogged fuel injectors; 2. Malfunction in the engine system causing the warning light to illuminate, such as faults in the throttle pedal sensor, throttle position sensor, or poor wiring connections; 3. Some vehicle transmission system faults are also indicated by the engine warning light, such as internal transmission faults, slipping, or overheating. Taking the Verano as an example: it is a mid-size sports sedan under SAIC-GM Buick, with a length, width, and height of 4723 mm, 1802 mm, and 1466 mm respectively, and a wheelbase of 2700 mm. In terms of appearance, the Verano features a winged chrome grille, winged LED automatic sensing headlights, winged LED taillights, and a fastback roof.
