Resetting the check engine light on a 2024 Toyota Sienna may be a quick electronic step, but it should only be done after diagnosing and correcting the underlying issue. At Larry H. Miller American Toyota Albuquerque we emphasize transparency: we won’t clear codes to silence the light without repairing the root cause because temporary resets can hide developing faults and lead to larger repairs later. Our technicians use genuine Toyota tools and OEM parts to restore proper operation, then clear codes and perform a verification drive to ensure the condition won’t recur. Choosing the dealership for a proper reset delivers immediate and long-term savings — you avoid repeated trips and cascading failures, benefit from warranty protection, and get documentation of the repair. We also provide service financing, clear estimates, and occasional service specials to make quality maintenance accessible.

2024 Toyota Sienna Check Engine Light Codes

Common check engine light codes for a 2024 Toyota Sienna include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim/system lean), P0300 (random/multiple cylinder misfire), and various oxygen sensor codes. Ignoring these codes can escalate costs: a P0420 left untreated may lead to a failed catalytic converter costing significantly more than addressing upstream sensor or fuel issues; P0300 misfires can damage engine components and reduce fuel economy; lean codes often signal vacuum leaks or sensor failures that lower performance and MPG. At Larry H. Miller American Toyota Albuquerque our certified technicians diagnose codes with factory tools, explain repair options, and outline how prompt, OEM-backed service produces immediate savings and prevents costly repairs down the road. We strive to be competitively priced — often costing less than independent shops when considering warranty coverage and long-term reliability.
