Engine Idle Setting Rheostat
Mitsubishi FUSO®

The Engine Idle Setting Rheostat, also known as MK344442, is an electrical component found in trucks that controls the idle speed of the engine. It helps regulate the amount of fuel and air entering the engine at idle, ensuring a smooth and steady operation. The rheostat works by varying the resistance in an electrical circuit that controls the engine's throttle position sensor. This allows the truck to maintain a consistent idle speed regardless of external conditions such as temperature or altitude. Proper maintenance and adjustment of the Engine Idle Setting Rheostat can help improve fuel efficiency and prolong the life of the engine.
