2019 Lexus LS 500 Check Engine Light Codes

At Park Place Lexus Grapevine in Grapevine, TX, our technicians see the full range of check engine light codes on the 2019 Lexus LS 500. Common codes include P0420 (catalyst system efficiency), P0300 (engine misfires), P0171/P0174 (fuel trim/system lean), and P0130 (oxygen sensor). Left unaddressed, these conditions can reduce fuel economy, damage the catalytic converter, or lead to engine failure—costing far more than timely repairs. For example, ignoring a misfire can damage the catalytic converter and lead to a repair bill several times higher than replacing spark plugs or coils early. Our dealership provides accurate diagnostics, OEM parts, and a clear repair plan to minimize future expenses. We often offer prices that beat independent shops when factoring in warranty coverage, long-term reliability, and the reduced risk of repeat failures. Use our schedule service page to book a diagnostic, and check our service specials for current savings.

A flashing light often signals ignition or fuel delivery faults that, if ignored, degrade the catalytic converter and lead to costly repairs.

We also promote cost-effective options through our service specials and offer service financing so you can address urgent repairs now and manage payments over time.
