2013 Toyota 4Runner Check Engine Light Codes

Common check engine light codes for a 2013 Toyota 4Runner include P0420 (catalyst efficiency below threshold), P0300–P0306 (random or cylinder-specific misfire), P0171/P0174 (fuel trim lean conditions), and P0135 (oxygen sensor heater circuit). Left unaddressed, P0420 can lead to full catalytic converter failure — a repair that is significantly more expensive than early diagnosis and sensor replacement. Misfire codes can cause rough running and reduced towing capacity, risking further engine damage; timely cylinder and ignition system checks prevent larger failures. Lean condition codes often indicate vacuum leaks or fuel system issues that reduce MPG and accelerate component wear. At Larry H. Miller Toyota Peoria, our diagnostics combine code reading with live data capture and visual inspection to determine precise causes and cost-effective fixes. We pride ourselves on competitive pricing that frequently undercuts independent shops when you consider OEM parts, technician training, and warranty-backed work.
