Common symptoms include the engine staying at idle despite moving the dial, or sudden RPM drops during operation. We recommend checking the harness first; if the wiring is intact, replacing the 7861934130 sensor usually restores full functionality.
Installation requires precise alignment with the throttle motor gears. Ensure the motor is at the stop position before mounting. After installation, a "throttle calibration" via the excavator monitor panel is required so the controller learns the new voltage range of the 7861-93-4130.
