2013 Toyota Highlander Check Engine Light Reset

Resetting the check engine light on a 2013 Toyota Highlander can be quick, but an immediate reset without diagnosis risks masking an underlying problem. At Larry H. Miller Toyota Peoria, our approach pairs an accurate scan with clear guidance: we read stored and pending trouble codes with factory tools, correct the root cause with OEM parts when required, then confirm that systems are operating within specifications before clearing codes. This protects engine and emissions systems and preserves long-term reliability. We provide transparent pricing and discuss immediate and long-term savings so you understand the value of doing the job right — often costing less over time than independent shops because our diagnostics and repairs avoid repeat visits. Warranty-covered repairs must be done at a certified dealership to remain valid, and we honor that promise. If you need to act now, you can schedule service online and check our current service specials. Service financing is available to help you get repairs today and pay over time.

2013 Toyota Highlander Check Engine Light Codes

Common check engine light codes for a 2013 Toyota Highlander include P0420 (catalyst efficiency), P0171/P0174 (lean condition), P0300–P0306 (misfires), and sensor-related codes like P0130–P0167 (oxygen sensor issues). Left unresolved, these codes can lead to reduced fuel economy, increased emissions, and progressive component damage that raises repair costs significantly — for example, an unresolved catalytic converter issue may escalate to a replacement that costs far more than timely sensor repairs. At Larry H. Miller Toyota Peoria in Peoria, AZ, we diagnose codes precisely and outline repair options, costs, and expected benefits so you can make a confident choice. Our certified technicians use OEM parts and follow Toyota procedures to ensure long-term performance and maintain warranty coverage on applicable repairs. We focus on convenience and customer experience: fast drop-off, clear estimates, and service financing options.

Check Engine Light Flashing

A flashing check engine light on your 2013 Toyota Highlander signals an active misfire or another condition that could damage the catalytic converter. This is a more urgent indicator than a steady light and requires immediate inspection. Driving with a flashing light risks further engine damage, loss of power, and much higher repair costs. At Larry H. Miller Toyota Peoria, we prioritize flashing-light diagnostics and often accommodate urgent appointments to protect your vehicle and safety. Our technicians perform a comprehensive evaluation using OEM diagnostic tools, present honest repair options, and explain warranty implications — remember, warranty-covered repairs must be performed at a certified dealership to remain valid.
