2025 Toyota Grand Highlander Check Engine Light Codes

Common check engine light codes for the 2025 Toyota Grand Highlander seen in Albuquerque include P0300 (random/multiple misfire), P0420 (catalyst efficiency), P0171/P0174 (system too lean), P0455 (EVAP large leak), and P0128 (coolant thermostat). Left untreated, P0300 can lead to engine damage and a failed catalytic converter—repair costs can escalate to thousands. P0420 often signals catalytic issues that affect emissions and performance, potentially requiring exhaust repairs. EVAP leaks like P0455 may be inexpensive to fix if caught early but allow fuel vapors to escape and can cause failed emissions tests. Addressing P0171 quickly prevents poor fuel economy and further sensor or catalytic damage. At Larry H. Miller American Toyota Albuquerque our technicians interpret these codes in context—diagnosing sensors, fuel systems, or mechanical faults—and provide transparent pricing and long-term savings by fixing the root cause.
