Yes, some Hyundai Sonata owners in Pakistan have reported issues with the check engine light illuminating due to problems with emission sensors. Common causes include faulty oxygen sensors o r issues with the exhaust gas recirculation EGR system. For instance, a 2020 Sonata owner experienced a persistent P0471 code, indicating a problem with the differential pressure sensor, which was eventually resolved by replacing the EGR valve . Regular maintenance and timely replacement of faulty components can help prevent such issues.
