2014 Lexus GX 460 Check Engine Light Codes

Common trouble codes on a 2014 Lexus GX 460 frequently point to oxygen sensors (P013x–P016x), EVAP system faults (P0440–P0457), and ignition or misfire codes (P0300–P0308). Left unresolved, an oxygen sensor fault reduces fuel economy and can accelerate exhaust system wear, potentially leading to costly catalytic converter replacement. EVAP leaks degrade emissions performance and can cause failed inspections; small repairs now avoid larger repairs later. Misfires, if ignored, risk engine damage and expensive repairs. At Park Place Lexus Grapevine in Grapevine, TX, our certified Lexus technicians diagnose code specifics with OEM-level tools and explain cost implications clearly—typically diagnostics followed by repair estimates. Choosing dealer service often costs less in the long run: correct parts, precise labor, and documented service history preserve vehicle value. We emphasize transparency, provide timeline and cost estimates, and offer service financing to get repairs started immediately. Check our service specials for current offers and schedule service to address codes before they escalate.
