2023 Lexus RX 350 Check Engine Light Codes
The check engine light on a 2023 Lexus RX 350 commonly returns codes such as P0420 (catalytic converter efficiency below threshold), P0171/P0174 (system too lean), P0300–P0304 (misfires), P0135/P0136 (oxygen sensor faults), and P0440 (EVAP system leak). Left unaddressed, these issues can escalate: a failing O2 sensor or small EVAP leak often causes higher fuel consumption and failed emissions testing; ignoring a lean condition or persistent misfire risks severe engine damage and a ruined catalytic converter, which can cost $1,000 to $2,500 or more to replace. At Park Place Lexus Grapevine in Grapevine, TX, we identify codes quickly using Lexus-grade scanners and communicate repair priorities so you can weigh immediate versus preventive fixes. Our certified technicians specialize in Lexus systems, and we use OEM parts to ensure compatibility and long-term performance. Choosing dealership service often results in lower total cost of ownership over time thanks to accurate diagnostics, warranty protection, and correct repairs the first time.

2023 Lexus RX 350 Check Engine Light Reset
Resetting the check engine light on a 2023 Lexus RX 350 can be as simple as clearing codes with a scan tool or, in older advice, disconnecting the battery — but resetting without correcting the underlying fault only postpones failure and can cause greater expense later.

Our process emphasizes transparency: you receive a clear diagnostic report, an itemized estimate, and an explanation of how recommended repairs protect fuel economy, emissions compliance, and drivability. Using OEM parts and manufacturer procedures preserves warranties and performance; note that warranty-covered repairs must be completed at a certified dealership to remain valid.

At Park Place Lexus Grapevine we treat flashing engine lights as priority service items and will triage your vehicle to limit further damage. Our technicians perform a targeted diagnostic to isolate misfires, examine ignition components, fuel delivery, and sensors, and deliver a transparent repair plan.
