When a Dodge's check engine light activates, it signals an array of possible issues--from minor faults like a loose fuel cap to more significant problems such as malfunctioning sensors or engine misfires--requiring immediate, data-driven diagnostics. Prioritizing fault codes obtained from an OBD-II scanner is essential; these codes pinpoint specific areas of concern, like oxygen sensor efficiency or catalytic converter performance, and guide technicians to address the highest-risk issues first. By focusing on key diagnostic data, one can efficiently identify and resolve underlying problems, ensuring that the Dodge maintains optimal engine performance and reliability.
