2026 Dodge Hornet Check Engine Light Codes

Common check engine light codes for a 2026 Dodge Hornet include P0420 (catalyst system efficiency), P0171/P0174 (fuel trim/mixture lean), and P0135/P0136 (oxygen sensor faults). Left unaddressed, a P0420 could reduce fuel economy and damage the catalytic converter—costing significantly more than timely diagnosis. Lean condition codes can cause poor throttle response and expensive repairs if neglected, while failing oxygen sensors lead to incorrect fuel delivery and higher emissions. At Larry H. Miller Dodge RAM FIAT Tucson in Tucson, AZ, we diagnose these codes fast with OEM-grade scanners and explain repair costs and benefits clearly. Our factory-trained technicians use OEM parts and follow manufacturer procedures, maintaining warranty protections and maximizing vehicle longevity.
