2025 Ram 2500 Check Engine Light Codes

The 2025 Ram 2500 commonly records codes such as P0300 (random/multiple misfires), P0420 (catalyst system efficiency low), P0442 (EVAP small leak), P0135 (oxygen sensor heater circuit), and P0171 (system too lean). In Denver, timely attention at Larry H. Miller Chrysler Dodge Ram FIAT Denver prevents these codes from escalating into far costlier repairs. For example, ignoring a P0420 can lead to catalytic converter damage that costs $1,000–$2,500 to replace; an untreated misfire (P0300) can ruin pistons or the catalytic converter, creating major engine expenses. Small EVAP leaks like P0442 often cost under $200 to fix, so diagnosing early saves both money and downtime. Our certified RAM technicians use OEM diagnostic tools, ensuring precise code interpretation and accurate labor estimates. Choosing our dealership often yields lower total ownership costs than multiple independent visits because we fix root causes, honor factory warranties, and use genuine parts.
