The first step in diagnosing a check engine light is to retrieve trouble codes using an OBD-II scanner to identify the underlying issue.
A faulty mass airflow (MAF) sensor can cause rough idling by providing incorrect air-fuel mixture readings to the ECU.
A faulty starter motor can prevent the engine from cranking, leading to a no-start condition.
A faulty water pump can lead to inadequate coolant circulation, causing the engine to overheat.
The Dynamic Stability Control (DSC) system helps prevent skidding and loss of control by applying selective braking.
A failing throttle position sensor (TPS) can send incorrect signals to the ECU, resulting in delayed throttle response.
