Engine warning light illumination can be analyzed from the perspective of engine systems, including the fuel supply system, ignition system, intake system, exhaust system, and various sensor components. Dirty sensor head: A contaminated sensor head or one polluted by magnetic materials may cause wheel speed sensor failure. If the wheel speed sensor frequently malfunctions after traveling through water, mud, or sandy areas, cleaning it may help. Consequences of wheel speed sensor failure: A faulty vehicle wheel speed sensor can lead to unstable engine idle, momentary stalling or engine shutdown during acceleration or deceleration, reduced engine acceleration performance, inaccurate speedometer display, and illumination of the engine warning light.
