2022 Lexus NX 250 Check Engine Light Codes
At Park Place Lexus in Plano, TX, we frequently see codes that reflect real-world driving conditions for the 2022 Lexus NX 250: P0300 random/multiple misfire, P0420 catalyst efficiency below threshold, P0171 system too lean, P0442 evap small leak, and oxygen sensor faults. Each code points to a condition that affects performance, emissions, or fuel economy. For example, uncorrected misfires will quickly damage the catalytic converter — a repair that can cost thousands if ignored. A persistent P0420 may signal converter degradation; leaving it unresolved reduces efficiency and can lead to failed emissions inspections. Evap leaks and loose caps often cost little to repair but cause increased fuel vapor loss and check-engine triggers. Our trained Lexus technicians in Plano use factory-grade tools to read codes, test systems, and recommend OEM parts repairs when needed. That approach minimizes repeated visits, protects warranty coverage, and delivers immediate and long-term savings. You can schedule service online, review our service specials, or ask our advisors about service financing to address needed repairs today.
