Instead of running at a smooth, constant hum, the engine will rev up high, drop low, and continuously cycle up and down. This happens because the actuator's internal windings or shaft are sticking, causing it to over-correct or lag behind the control signals.\u003c\/p\u003e\n\u003cp data-path-to-node=\"5\"\u003e\u003cb data-path-to-node=\"5\" data-index-in-node=\"0\"\u003e2.

The engine might fire up briefly using residual fuel or starter fluid, but it will immediately die because the actuator cannot maintain the mechanical throttle opening.\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer information\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eCummins®\u003c\/strong\u003e is a worldwide leader in the production of engines, agricultural components, and other power-generating devices for various industries, including medium and heavy duty trucks, light commercial vehicles, buses, agriculture, and construction.
