What are the reasons for the engine fault light in a Buick car?
1 Answers
Buick car engine fault light is on due to: 1. Poor gasoline quality leading to incomplete combustion of the mixture in the cylinder, resulting in carbon deposits; 2. Excessive engine mileage causing weakened spark plug performance; 3. Aging vehicle mechanics; 4. Damage, poor contact, or signal interruption in water temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. Buick models include: Buick GL8, Buick Excelle, Buick Regal, Buick LaCrosse, Buick Envision, etc. Taking the 2021 Buick GL8 as an example, it is an MPV with body dimensions of: length 5238mm, width 1878mm, height 1776mm, and a wheelbase of 3088mm.
