To determine if the leak detection pump on a 2001 Dodge Dakota is bad, check for symptoms such as the check engine light being illuminated, especially if it indicates an EVAP system issue. You can also inspect for unusual smells of fuel around the vehicle or listen for the pump not operating during a self-test. Additionally, performing a smoke test on the EVAP system can reveal leaks or a malfunctioning pump. If you find any of these signs, the pump may need to be replaced.
