Check Engine Light Reset
The process to reset a check engine light on a 2023 Lexus NX 350 begins with a full diagnostic to identify and repair the underlying code. Resetting the light without fixing the root cause can mask issues and lead to larger failures, so our Park Place Lexus technicians in Plano, TX first read and interpret stored trouble codes using OEM-grade tools. We explain the diagnosis in plain terms, provide a clear estimate, and recommend OEM parts to restore factory performance. Choosing the dealership for a reset delivers measurable benefits: certified Lexus technicians, authentic parts, recorded service history to protect warranty coverage, and a documented repair that preserves resale value. We also provide transparent pricing and emphasize the long-term savings that come from correct repairs—our accurate diagnostics prevent repeat visits and additional expense. If the issue is minor and resolved, we will reset the system and perform follow-up checks to ensure the code does not return.

We also offer service financing so you can get necessary repairs now and pay over time, keeping your 2023 Lexus NX 350 protected without delay.
2023 Lexus NX 350 Check Engine Light Codes
Park Place Lexus in Plano, TX regularly sees a range of common check engine light codes on the 2023 Lexus NX 350—P0420 (catalytic converter efficiency), P0300 (random/multiple misfires), P0171/P0174 (fuel trim/fuel system lean), and sensor-related codes like P0135 (oxygen sensor heater). Each code carries specific risks when ignored: a P0420 can indicate failing catalytic performance that, if not addressed, leads to higher emissions and potential engine damage; left unresolved, repair costs rise sharply. Random misfires (P0300) can cause catalytic damage, decreased fuel economy, and drivability issues. Fuel trim codes often start as small sensor or vacuum issues but can escalate to expensive repairs and reduced engine life. At Park Place Lexus, our team uses OEM diagnostic procedures to quantify the problem, show cost-effective repair options, and discuss long-term savings from timely service. We emphasize convenience—same-day inspections when possible, genuine parts, and warranty-backed repairs—so you avoid repeat visits and costly downstream failures.
