FAQ

Q1: How can I confirm if this 227-7658 / 247-5230 sensor fits my Caterpillar 320C excavator?

First, locate your original sensor on the engine. The part number is usually etched or printed on the sensor body or connector housing. Cross-reference that number with 227-7658 or 247-5230. Additionally, check your machine’s serial number prefix against Caterpillar’s parts database for the 320C model. If your original number matches either of these, it is the correct replacement.

Q2: What are the common symptoms of a failing throttle positioner sensor on a 320B or 320C?

Common symptoms include erratic engine speed, surging at idle, poor acceleration response, unexpected engine shutdowns, and the illumination of the check engine light. You may also notice a decrease in fuel efficiency or difficulty starting the engine. If you observe any of these issues, testing or replacing the sensor is recommended.

Q3: What is the installation procedure for this sensor, and are there any special tools required?

Installation is generally a direct bolt-on replacement. Disconnect the battery, unplug the electrical connector from the old sensor, remove the mounting bolts, and install the new sensor in the reverse order. Ensure the throttle linkage is correctly aligned. Basic hand tools (wrenches and sockets) are typically sufficient. It is crucial to perform a throttle calibration or “learn” procedure using a diagnostic tool after installation to ensure the ECU recognizes the new sensor’s range. Always consult your machine’s service manual for specific torque specs and calibration steps.
