2010 Toyota Highlander Check Engine Light Codes

The 2010 Toyota Highlander commonly records codes related to emissions, oxygen sensors, EVAP system leaks, and ignition components. In Albuquerque, Larry H. Miller American Toyota Albuquerque routinely sees P0420 (catalyst efficiency below threshold), P0455 (EVAP large leak), and P0135 (oxygen sensor heater circuit). Left unaddressed, each can lead to specific costs: an unchecked EVAP leak can cause failed emissions tests and poor fuel economy; a failing oxygen sensor or catalytic converter increases fuel use and can cascade into costly exhaust repairs; ignition faults can cause engine misfires that damage catalytic converters and increase repair bills substantially. Our technicians use Toyota-specific diagnostics to pinpoint the cause quickly, avoiding unnecessary part replacements and repeat visits. Choosing our dealership means OEM parts, factory-trained technicians, and diagnostic accuracy that often delivers immediate and long-term savings compared with independent shops. We also honor warranty requirements—repairs covered under warranty must be performed at a certified dealership—and we offer service financing to spread payments.

2010 Toyota Highlander Check Engine Light Reset

Resetting the check engine light on a 2010 Toyota Highlander can be a temporary measure, but it doesn’t resolve underlying faults. Our dealership explains why dealership-performed resets paired with a full diagnostic are the responsible choice: we use OEM-grade tools to read and clear codes while documenting pending issues and repairs that protect warranty coverage and vehicle longevity. Independent code-clearing tools may erase a symptom without identifying the root cause, risking repeated breakdowns and increased long-term costs. At Larry H. Miller American Toyota Albuquerque we combine transparent pricing, factory-trained technicians, and verified OEM parts so you get reliable repairs and documented service history that enhances resale value. If the light is merely due to a loose gas cap, we’ll correct it and verify system readiness; if deeper issues exist, we’ll provide a clear estimate and financing options so you can proceed without delay. For convenience, schedule service online and check current service specials to save on recommended maintenance. Our approach prioritizes accuracy, safety, and the long-term health of your Highlander.
