2022 Lexus RX 350 Check Engine Light Codes

At Stevinson Lexus of Frederick in Frederick, CO, we see recurring codes for the 2022 Lexus RX 350 that owners should address promptly. Popular codes include P0420 (catalyst system efficiency below threshold), P0171/P0174 (system too lean), P0300–P0306 (misfires), and P0130–P0167 (oxygen sensor circuits). Ignoring a P0420 can lead to degraded emissions performance and eventual catalytic converter failure—repairs that become far more expensive if delayed. Lean condition codes (P0171/P0174) often trace to vacuum leaks, fuel system faults, or failing sensors; left unchecked these reduce MPG and can accelerate component wear. Misfires can damage catalytic converters and cause drivability issues; prompt attention prevents long-term engine and exhaust damage. Stevinson Lexus of Frederick uses factory diagnostic procedures to pinpoint causes quickly, which reduces diagnostic labor and avoids unnecessary parts replacement—producing immediate and long-term savings for our customers. Our certified Lexus technicians document findings and provide clear estimates; repairs covered under warranty are performed at our dealership to ensure coverage remains valid. To prioritize service, schedule service online and check current service specials that can lower your out-of-pocket costs.

Our service team will prioritize a full scan, road test, and targeted testing to identify ignition, fuel, or sensor faults that cause flashing conditions.
