Can Insufficient Turbocharging Cause the Engine Malfunction Light to Illuminate?

[LorenzoRose]

Insufficient turbocharging can cause the engine malfunction light to illuminate. The reasons for the engine malfunction light turning on are as follows: 1. Damaged air flow meter: Although many car models now use turbocharged engines, many mid- to low-range models still employ naturally aspirated engines. For instance, Mazda has openly stated it will not follow the trend of equipping turbocharged engines. In common naturally aspirated engine models, a certain component can directly cause the engine malfunction light to illuminate. 2. Engine misfire: Besides the air flow meter, engine misfire can also trigger the malfunction light. Engine misfire means that during operation, one of the ignition cycles fails to occur. This causes the engine to run intermittently or stop, and this abnormal state is recorded by the engine control unit, leading to the illumination of the engine malfunction light.
