Engine Idle Setting Rheostat
Mitsubishi FUSO®

The Engine Idle Setting Rheostat, also known as the idle control module, is a crucial component of a commercial truck's engine management system. This part is responsible for regulating the engine's idle speed, which is the rotational speed of the engine when the vehicle is stationary. The rheostat achieves this by controlling the amount of electrical current that flows to the engine's idle air control valve. Without the Engine Idle Setting Rheostat, the engine may idle too high or too low, which can cause a range of issues such as poor fuel economy, stalling, and difficulty starting the engine. Therefore, it is important to ensure that this part is functioning properly to maintain the optimal performance of the engine and the vehicle as a whole.
