2014 Toyota Highlander Hybrid Check Engine Light Reset

Resetting a check engine light on a 2014 Toyota Highlander Hybrid is more than clearing an alert — it’s about confirming the underlying issue is fixed and ensuring lasting reliability. While some drivers use code readers to reset a light, doing so without addressing the root cause risks repeat failures, hidden damage, or losing warranty protections. At Larry H. Miller Toyota Murray in Murray, UT, we combine a full diagnostic with OEM procedures so resets reflect true repairs. Our factory-trained technicians verify all systems, replace genuine Toyota parts when necessary, and document repairs so you maintain warranty coverage. We also provide transparent estimates and explain long-term savings: fixing a failing oxygen sensor or EVAP fault now prevents reduced fuel economy and expensive catalytic converter damage later. To protect your Highlander’s performance and resale value, schedule service online, and see current discounts in our service specials. We offer service financing to help you get repairs done today and pay over time.

2014 Toyota Highlander Hybrid Check Engine Light Codes

Common codes for the 2014 Toyota Highlander Hybrid include P0420 (catalyst system efficiency low), P0133/P0135 (oxygen sensor slow/faulty), P0300 (random/multiple misfires), and P0455/P0442 (EVAP system leak). Ignoring these codes can lead to escalating costs: an unfixed P0420 can eventually require catalytic converter replacement — often $1,000+ — while persistent misfires may damage the catalytic converter and engine internals. At Larry H. Miller Toyota Murray we diagnose codes quickly, explain repair priorities, and use OEM parts that protect performance and longevity. Our service team in Murray, UT provides a comfortable waiting area, shuttle service, and efficient repair schedules so you spend less time off the road.

Miller Toyota Murray, our technicians prioritize flashing-light diagnostics and use OEM diagnostic tools to identify ignition or fuel system faults, sensor failures, or software-related causes.
