2022 Lexus RC 300 Check Engine Light Codes
Understanding common check engine light codes for the 2022 Lexus RC 300 helps owners in Grapevine, TX make informed decisions. Typical codes include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), and P0171/P0174 (fuel trim/lean condition). Left unresolved, a P0420 can lead to failed emissions testing and costly catalytic converter replacement; early diagnosis can limit repairs to sensors and prevent converter damage. A P0300 requires prompt attention to avoid internal engine wear and greater repair bills, while P0171/P0174 often point to vacuum leaks or fuel delivery issues that are inexpensive to fix when caught early.
