Why does my Hyundai’s check engine light keep coming on due to sensor problems?

My Hyundai car’s check engine light frequently turns on, and mechanics say it’s because of faulty sensors. Which sensors commonly fail in Hyundai cars in Pakistan, and how can I diagnose the exact issue?

The check engine light CEL can be triggered by various faulty sensors, including oxygen sensors, mass airflow sensors, o r crankshaft position sensors. Common causes in Pakistan include:

Dust and dirt accumulation affecting sensor performance.

Poor fuel quality leading to sensor contamination.

Electrical issues like corroded wiring o r loose connectors.

Diagnosis: A mechanic uses an OBD-II scanner to read error codes pinpointing the faulty sensor. Early diagnosis prevents further engine damage.
