Understanding common check engine light codes for a 2023 Jeep Cherokee helps you make smarter decisions. Frequent codes include P0420 (catalytic converter efficiency), P0300 (random/multiple cylinder misfire), P0171/P0174 (lean condition), and P0133 (oxygen sensor slow response). Left unaddressed, these can reduce fuel economy, increase emissions, and lead to major component failures that raise repair costs significantly. At Larry H.
