What Causes the Car Engine Warning Light to Come On?

[JoyAnn]

Car engine warning lights are typically caused by sensor issues. Here is some relevant information about engines: 1. Introduction: An engine is a machine that can convert non-mechanical energy into mechanical energy. 2. Classification: Engines include internal combustion engines, external combustion engines, jet engines, electric motors, etc. External combustion engines convert the thermal energy generated by combustion into kinetic energy, with Watt's improved steam engine being a classic example. Internal combustion engines, specifically reciprocating piston engines, differ most significantly from external combustion engines in that their fuel burns internally. Jet engines are those that directly generate reactive thrust through high-speed airflow ejected from nozzles.
