2013 Toyota Avalon Hybrid Check Engine Light Codes

The most common codes we see on a 2013 Toyota Avalon Hybrid at Larry H. Miller Toyota Murray in Murray, UT, include P0420 (catalyst system efficiency), P0455 or P0442 (EVAP large or small leak), P0300 (random/multiple cylinder misfires), and P0171 (system too lean). Each code points to different risks and costs if ignored: a persistent misfire (P0300) can overheat and destroy a catalytic converter, turning what could have been a modest ignition repair into a $1,000–$2,500 parts-and-labor replacement; an unchecked EVAP leak can fail emissions tests and degrade fuel economy; failing oxygen sensors or lean conditions reduce efficiency and increase long-term wear. At Larry H. Miller Toyota Murray our factory-trained technicians use OEM diagnostic tools to determine whether the issue is simple (tighten gas cap, replace a sensor) or requires deeper repair. We provide transparent cost estimates before work begins, explain the long-term savings of correct repairs, and apply OEM parts and warranty-backed labor to protect your investment.
