2010 Toyota 4Runner Check Engine Light Codes

At Larry H. Miller American Toyota Albuquerque we see a range of diagnostic trouble codes on the 2010 Toyota 4Runner. Typical codes include P0420 (catalyst efficiency below threshold), P0171 (system too lean), P0300 (random/multiple cylinder misfire), P0455 (large EVAP leak), and P0128 (thermostat/heating issue). Left unaddressed, a P0420 can lead to catalytic converter failure and costly replacement; failing to correct P0171 or P0300 accelerates wear and reduces fuel economy, increasing operating costs. A P0455 that goes ignored can allow fuel vapors to escape, failing emissions tests and possibly causing a check engine recurrence. Our certified Toyota technicians use OEM parts and factory procedures to diagnose codes accurately and recommend targeted repairs that prevent escalation. Choosing dealership service means accurate root-cause fixes, transparent estimates, and documented maintenance that supports vehicle resale value. We combine quick diagnostics with comfortable customer amenities, loaner options, and clear communication so Albuquerque drivers get efficient repairs and immediate plus long-term savings.
