2016 Hyundai Sonata Check Engine Light Reset

Resetting the check engine light on a 2016 Hyundai Sonata is straightforward with an OBD-II scanner, but clearing codes without fixing the cause can hide progressive damage.

Choosing dealer service means transparent estimates, OEM parts, certified technicians, and warranty protection—factors that preserve vehicle value and reduce long-term expense. We also include battery and charging checks during diagnostics to ensure a weak battery isn’t causing intermittent codes.

2016 Hyundai Sonata Check Engine Light Codes

Common check engine light codes for a 2016 Hyundai Sonata include P0420 (catalyst efficiency), P0300 (random/multiple cylinder misfires), P0171 (system too lean), P0455 (large EVAP leak), and P0128 (coolant thermostat). If not addressed, these can escalate: misfires (P0300) may damage pistons and the catalytic converter and lead to costly repairs; P0420 left unchecked can fail emissions tests and require expensive catalyst replacement; EVAP leaks lower fuel economy and trigger recurring warning lights. Herb Chambers Hyundai of Auburn in Auburn, MA focuses on accurate diagnostics to prevent repeated, unnecessary repairs.
