Yes, a faulty Intake Cam Position (ICP) sensor on a 3.8L Dodge minivan can absolutely cause it to quit running. The ICP sensor is crucial for the engine's timing. If it malfunctions or fails, the engine computer (PCM) won't receive accurate information about the camshaft's position, leading to improper fuel injection and ignition timing. This can result in a rough running engine, misfires, and ultimately, a complete engine stall or inability to start.
While other components can also cause a similar problem, a failing ICP sensor is a strong possibility. A diagnostic scan by a mechanic is recommended to determine the exact cause.
