Check Engine Light Reset
The check engine light reset on a 2024 Toyota Grand Highlander Hybrid goes beyond clearing a dashboard warning — it should be the final step after identifying and repairing the underlying fault. Our technicians at Larry H. Miller American Toyota Albuquerque use factory-level diagnostic tools to retrieve and interpret stored trouble codes, verify repairs, and then perform a controlled reset so you have confidence the issue will not recur. A professional reset at our dealership includes confirmation that the repair restored proper system operation and that no pending codes remain. This approach prevents misleading resets that mask in-progress failures and often leads to higher long-term expenses. We pair transparency with OEM parts and Toyota-trained technicians, and any warranty-covered repairs must be completed at a certified dealership to maintain coverage. For convenience, check our current service specials and consider our service financing if you prefer to pay over time. To protect your vehicle and ensure the work is done right the first time, schedule service with us today.
2024 Toyota Grand Highlander Hybrid Check Engine Light Codes
Common check engine light codes for the 2024 Toyota Grand Highlander Hybrid include P0420 (catalyst system efficiency low), P0171/P0174 (fuel system lean), P0300 (random/multiple cylinder misfire), and P0135/P0136 (oxygen sensor heater circuit). Each code points to specific systems and consequences if left unaddressed: a persistent P0420 can mean a failing catalytic converter — neglecting that can lead to much higher exhaust and emissions repair bills; P0300 misfires, if ignored, can damage pistons, spark plugs, and converters; P0171 lean conditions frequently point to vacuum leaks or sensor issues that reduce fuel economy and accelerate drivetrain wear. At Larry H. Miller American Toyota Albuquerque we provide a clear estimate for each repair scenario and explain immediate versus long-term costs so you can make informed decisions. Our certified technicians use genuine Toyota parts and OEM procedures to prevent repeat failures and extend vehicle life. To save on maintenance, view our service specials, and when you’re ready, schedule appointment for a certified inspection that protects both performance and resale value.
Check Engine Light Flashing
A flashing check engine light on a 2024 Toyota Grand Highlander Hybrid signals a severe condition — most often an active and damaging engine misfire.

Our service team will prioritize safety, perform a fast scan, and isolate causes like ignition, fuel delivery, or sensor failures. We emphasize fast turnarounds, warranty protection, and correct OEM repairs to minimize downtime and avoid repeat visits.
