2015 Toyota 4Runner Check Engine Light Reset

Resetting the check engine light on a 2015 Toyota 4Runner might seem simple, but a reset alone won’t solve underlying faults. At Larry H. Miller American Toyota Albuquerque we emphasize correct diagnosis before reset — our factory-trained technicians read trouble codes with OEM-level tools, address the root cause, then clear codes so you’re not masking ongoing issues. Using genuine Toyota parts and dealer-level calibration ensures sensors, emissions systems, and engine controls behave to factory specifications. That transparency protects warranty coverage (repairs under warranty must be performed at a certified dealership) and delivers long-term savings by preventing repeat visits. We also provide clear estimates, documented repairs, and often run service specials to reduce immediate costs. If you need a convenient time to bring your 2015 Toyota 4Runner in, schedule service online and choose a slot that works for you—our team in Albuquerque will confirm the diagnostic steps and expected turnaround before any work begins.

2015 Toyota 4Runner Check Engine Light Codes

Common codes for a 2015 Toyota 4Runner include P0420 (catalytic converter efficiency), P0135 (oxygen sensor heater), P0300 (random/multiple misfires), and P0456 (small EVAP leak). Left unfixed, these can increase fuel costs, accelerate component wear, and lead to larger repairs—catalytic converter failures or engine damage can cost thousands. At Larry H. Miller American Toyota Albuquerque we map each code to a clear repair plan, use OEM parts, and explain immediate and lifetime savings from prompt service. Many customers find our bundled diagnostics and repair packages often cost less than independent shops when you factor in accurate diagnostics, correct parts, and warranty protection. We also offer service financing for unexpected repairs and run local service specials for added value.

Check Engine Light Flashing

A flashing check engine light on a 2015 Toyota 4Runner usually signals a severe misfire or condition that can damage the catalytic converter or engine if driven. This requires immediate attention—do not continue normal driving. At Larry H. Miller American Toyota Albuquerque we treat flashing lights as priority service: our certified technicians perform rapid diagnostics, isolate ignition, fuel, and sensor faults, and recommend OEM repairs to protect your vehicle’s performance and emissions systems. We back work with transparent pricing, warranty guidance (warranty repairs must be completed at certified dealerships), and options for service financing so you can address urgent repairs now and pay over time.
