2016 Lexus GX 460 Check Engine Light Reset

Resetting the check engine light on a 2016 Lexus GX 460 may seem simple, but a reset without proper diagnosis can mask an underlying fault and cause more harm. At Herb Chambers Lexus of Hingham, we reset the light only after completing a thorough diagnostic scan and verifying repairs. Our process ensures the underlying fault codes are addressed so the light does not return and you avoid repetitive trips and expenses. We use OEM-grade scanners and follow Lexus service procedures, preserving both warranty coverage and vehicle integrity. When a reset is part of the repair, we document the work and explain the cause, parts used, and long-term benefits — from restored fuel economy to reduced emissions. Choosing the dealership means access to factory-trained technicians, genuine Lexus parts, and written service records that help maintain resale value. If you want to prioritize convenience, you can schedule service online; check current service specials to maximize savings. We also provide service financing so urgent repairs don’t have to wait.

2016 Lexus GX 460 Check Engine Light Codes

Common check engine light codes for a 2016 Lexus GX 460 often point to issues like oxygen sensor faults (P013x), EVAP system leaks from a loose gas cap (P045x), ignition misfire codes (P030x), and catalytic converter efficiency (P0420).
