2023 Kia Sorento Check Engine Light Codes

Common check engine light codes for a 2023 Kia Sorento include P0420 (catalytic converter efficiency), P0300–P0304 (random or cylinder-specific misfires), P0130–P0167 (oxygen sensor issues), and P0455 (EVAP leak). Each code carries different consequences if ignored: an unresolved P0420 can lead to costly catalytic converter replacement, misfire codes can cause engine damage and poor fuel economy, faulty oxygen sensors increase emissions and degrade performance, and EVAP leaks reduce efficiency and may fail emissions testing. At Herb Chambers Kia of Burlington in Burlington, MA, our certified technicians interpret codes in the context of vehicle history and real-world symptoms, giving you a prioritized repair plan that balances cost, urgency, and long-term savings. We use OEM parts, perform repairs to Kia standards, and stand behind our work with dealership warranties — and any warranty work should be done at a certified dealership to ensure coverage remains intact.
