2010 Hyundai Azera Check Engine Light Codes

At Larry H. Miller Hyundai Peoria in Peoria, AZ, we frequently diagnose common codes on the 2010 Hyundai Azera such as P0130 (O2 sensor), P0420 (catalyst efficiency), P0300 (random/multiple cylinder misfire), and P0171/P0174 (fuel trim/lean conditions). Each of these codes points to different root causes: an oxygen sensor or wiring issue left untreated can reduce fuel economy and damage the catalytic converter; P0300 misfires left unaddressed can stress ignition components, catalytic systems, and the engine itself; lean conditions can indicate vacuum leaks or fuel system problems that reduce performance and increase wear. The costs of ignoring these issues compound — what might start as a sensor replacement can escalate to catalytic converter replacement, ignition coil and spark-plug replacement, or even more extensive engine repairs. Our Hyundai-certified technicians use OEM parts and factory diagnostic procedures to deliver accurate fixes, preserving vehicle longevity and resale value. We provide clear estimates and often deliver better immediate and long-term savings than independent shops because of factory warranties, OEM parts, and efficient diagnostics. For convenience, explore our service specials, or schedule service to get priority diagnosis and transparent next steps.
