2022 Lexus LX 600 Check Engine Light Codes
The Park Place Lexus service center in Plano, TX, routinely diagnoses the most common codes that illuminate the check engine light on a 2022 Lexus LX 600. Typical codes include P0420 (catalyst system efficiency below threshold), P0300 (random/multiple cylinder misfire), P0171/P0174 (lean fuel trim), P0130–P0167 (oxygen sensor faults), and P0455 (EVAP large leak). Ignoring these codes can escalate costs quickly: an oxygen sensor left unaddressed lowers fuel economy and can accelerate catalytic converter wear (replacement can exceed $1,500–$3,000), unresolved misfires risk internal engine damage and higher repair bills, and EVAP leaks reduce emissions compliance and network performance. Park Place Lexus offers precise OEM diagnostics that identify the underlying cause so you only pay for necessary work. Our factory-trained technicians, genuine Lexus parts, and clear estimates reduce long-term ownership costs—improving fuel economy, preserving resale value, and preventing costly downstream repairs. Take advantage of transparent pricing and ongoing maintenance plans; to get started, schedule service and check our service specials for current savings.
2022 Lexus LX 600 Check Engine Light Reset
Resetting the check engine light on a 2022 Lexus LX 600 is straightforward but should be done only after verifying and correcting the underlying issue.

At Park Place Lexus in Plano, TX, we use OEM-grade diagnostic tools to capture freeze-frame data and live engine parameters so the reset reflects a verified repair. Our approach delivers transparency: you receive a detailed report of codes found, parts recommended, and any warranty-eligible coverage. Choosing the dealership means OEM parts, certified technicians, and service records that protect your vehicle’s value. We also provide service financing to help make repairs manageable and immediate savings through exclusive service specials. For a professional reset and repair plan you can trust, schedule service with Park Place Lexus today.
