What are the reasons for the power system warning light to illuminate?
1 Answers
Engine warning light illumination is usually caused by the following reasons: 1. Poor combustion condition: Poor engine combustion is the main cause of the engine warning light. During vehicle operation or at the moment of ignition, the engine warning light on the dashboard (usually red or yellow) illuminates. In most cases, it won't disappear automatically, though it may in rare instances. 2. Engine knocking: In the first scenario, some engine warning lights may illuminate while others may not. In the second and third scenarios, the engine warning light will inevitably illuminate. 3. Internal causes for engine warning light illumination: Poor fuel quality; Dirty engine cylinders with carbon deposits. Over time, engines inevitably accumulate carbon deposits, which alter the engine's design parameters and, due to their unstable nature and heat retention, can cause irregular ignition leading to engine knocking. 4. Cooling system issues such as piston scuffing, knocking, cylinder leakage, severe noise generation, and reduced acceleration power: These occur due to abnormal engine operating temperatures, excessive pressure, and poor cooling system conditions. A malfunctioning cooling system directly prevents the engine from operating at normal temperatures, resulting in the aforementioned severe issues.
