2011 Toyota Highlander Check Engine Light Codes

At Larry H. Miller Toyota Murray in Murray, UT, we see recurring codes on the 2011 Toyota Highlander that owners should know about: P0420 (catalyst system efficiency below threshold), P0135/P0141 (oxygen sensor heater circuit), P0300–P0306 (random/misfire), and P0455 (large fuel system leak). Left untreated, P0420 can lead to poor emissions compliance and costly catalytic converter replacement; early diagnosis minimizes parts and labor costs. Oxygen sensor faults reduce fuel economy and increase emissions; addressing them promptly restores efficiency and can prevent catalytic damage. Misfire codes, if ignored, risk piston and catalytic damage and can escalate repair bills dramatically. A P0455 can cause drivability and fuel-evaporation issues and may be as simple as a faulty gas cap or as involved as a repair to fuel lines or EVAP components.

Our Murray service center uses Toyota factory diagnostic procedures and OEM parts to isolate root causes quickly, which reduces overall expense and downtime. We document findings and provide clear estimates so you understand both immediate costs and long-term savings from proper repairs. Choosing Larry H. Miller Toyota Murray means certified technicians, genuine parts, fast turnaround, and a comfortable waiting area with amenities. We routinely highlight relevant service specials to lower your out-of-pocket expense and offer service financing to spread payment when needed. That combination of transparency and expertise preserves your Highlander’s longevity and resale value while saving money over repeated visits to lesser-equipped shops.
