Product Description
The Bendix K136300 ET-2 Electronic Throttle Potentiometer Kit is a genuine replacement assembly designed for compatible commercial vehicles equipped with Cummins CELECT electronic engine control systems. This kit replaces the original throttle position potentiometer, helping restore accurate communication between the accelerator pedal and the engine's electronic control module (ECM).
The ET-2 electronic throttle uses a potentiometer to convert accelerator pedal movement into an electrical signal that communicates the driver's requested engine speed. As the pedal moves, the potentiometer changes its electrical output, allowing the engine control system to regulate throttle response and fuel delivery.
A worn or malfunctioning potentiometer can cause inconsistent throttle response, acceleration problems, or electronic throttle fault codes. Replacing a defective component with the correct Bendix kit helps restore dependable accelerator operation.

The K136300 provides the components needed to service the potentiometer portion of a compatible ET-2 electronic throttle assembly without replacing the complete accelerator pedal mechanism.
Before ordering, verify the original potentiometer part number, engine control system, electrical connector, and throttle assembly configuration. Bendix ET-2 potentiometers are engine-specific and are not universally interchangeable.
Proper installation and adjustment are essential. Follow Bendix service procedures for potentiometer positioning, electrical testing, and throttle calibration before returning the vehicle to service.
Important fitment distinction: Bendix K136300 is an ET-2 potentiometer kit for compatible Cummins CELECT systems. It is not a complete throttle pedal assembly, and compatibility should be confirmed using the original potentiometer or treadle identification number.
