2010 Chrysler 300 Check Engine Light Codes

Common check engine light codes for a 2010 Chrysler 300 include P0300 (random/multiple cylinder misfire), P0420 (catalyst system efficiency below threshold), P0171/P0174 (fuel trim system lean), and P0456 (small EVAP leak). Each code points to different urgency and cost: ignoring a misfire (P0300) can lead to catalytic converter failure and much higher repair bills; unaddressed P0420 may require catalyst replacement; lean condition codes often trace to vacuum leaks or fuel delivery issues that, when fixed early, avoid fuel economy losses and larger repairs.
