The 0401 code on a 1996 Ford Ranger typically indicates an issue with the EGR (Exhaust Gas Recirculation) system, specifically that the EGR flow is insufficient. This could be due to a clogged EGR valve, a malfunctioning EGR sensor, or issues with the vacuum lines that control the EGR system. It's important to inspect these components for proper function, as they play a critical role in reducing emissions and ensuring optimal engine performance. Regular maintenance and addressing the code promptly can prevent further engine issues.
