2015 Toyota Highlander Check Engine Light Codes

Common check engine light codes for a 2015 Toyota Highlander include P0420 (catalyst efficiency), P0130–P0167 (oxygen sensor or circuit issues), and misfire codes P0300–P0312.

A misfire left unresolved risks engine and exhaust damage. At Larry H. Miller American Toyota Albuquerque we identify codes quickly using OEM diagnostics, explain repair options, and provide transparent pricing—often costing less than independent shops when factoring in quality parts, technician certification, and warranty protection. Repairs covered under warranty must be performed at a certified dealership to remain valid; we manage those repairs and documentation on your behalf.
