The 247-5230 is a Throttle Position Sensor (also referred to as a Governor
Motor Sensor or Potentiometer) used in Caterpillar (CAT) heavy machinery. It
monitors the position of the throttle motor to ensure precise engine speed and
response.
Common Vehicle & Engine Fitment
This sensor is a standard component for many "Dash B," "Dash C," and "Dash
D" series Caterpillar excavators:
Excavators: E320B, E320C, E320D, and 315B L.
Engines: Caterpillar 3066, 3054, and C6.4 diesel engines.
Key Specifications
Part Numbers: 247-5230, 2475230 (Interchangeable with 227-7658).
Type: Throttle Motor Positioner Sensor / Potentiometer.
Material: High-durability ABS or metal alloy designed for high-temperature
environments.
Connector: Typically a direct-install plug designed for the governor motor
assembly.
Installation & Troubleshooting
Direct Replacement: Designed as a "plug-and-play" fit for the throttle motor
assembly.
Critical Warning: Ensure the engine is off and the battery is disconnected
before replacing the sensor to avoid electrical damage to the ECU.
Calibration: After installation, it is often necessary to check the throttle cable
tension and ensure the 7-pin connector is clean and free of corrosion.
Symptoms of Failure: Inconsistent engine RPM, failure to reach full throttle,
or diagnostic codes related to throttle position signal voltage.
