Ford High Idle Throttle

The ETM51 throttle module has four selectable modes of fast engine idle operation, including three adjustable preset fixed speeds and one variable speed control via an external potentiometer. Select the mode by applying +12 volts to the RPM1, RPM2 or RPM3 terminal. The three presets can be individually adjusted by calibration potentiometers accessible on the top of the module. Ten LEDs display the selected operating mode, system status, and error conditions. The ETM51 controller module is compact, measuring only 2 x 4 inches. Wiring terminations utilize 0.25-inch Faston blade terminals. Its circuitry is encapsulated for maximum environmental protection.
