2017 Toyota Avalon Hybrid Check Engine Light Codes

The check engine light on a 2017 Toyota Avalon Hybrid commonly points to a handful of diagnostic trouble codes (DTCs) that our Larry H. Miller American Toyota Albuquerque team sees regularly. Typical codes include P0420 (catalyst system efficiency low), P0135 (oxygen sensor heater circuit), P0442 (EVAP system small leak), and P0300 (random/multiple cylinder misfire). Left unaddressed, these issues lead to lower fuel economy, failed emissions tests, poor drivability, and in some cases expensive repairs such as catalytic converter replacement (often exceeding $1,000). At our Albuquerque service center, we use Toyota factory scanners to identify the exact code and provide a clear estimate for repair versus replacement options. Relying on genuine OEM parts and certified technicians delivers better long-term value and can often cost less than independent shops because we eliminate unnecessary work and protect your vehicle’s warranty. To take action now, schedule service and review our current service specials.

Our factory-trained technicians explain why a reset was performed, what repairs were completed, and how the fix saves you money over time by preventing collateral damage or premature part replacement.
