Case IH 11061 – AUX67 or AUX89: 1st remote FLOW potentiometer is failed low
Issue description
The controller is receiving a voltage signal from the flow control potentiometer (located in the armrest for the first electro-hydraulic remote valve) that is below the acceptable minimum threshold. This typically points to a failed potentiometer, an open circuit, or a short to ground in the wiring.

Check the cause
Inspect the wiring harness and connector leading to the 1st remote flow potentiometer inside the armrest for pinched wires, loose pins, or a short to ground.
Check the potentiometer for physical damage or a dead spot.
Attempt to recalibrate the remote valves via the A-post display to see if the controller can read the potentiometer's sweep. If the A-post display shows the remote is stuck in a specific position or fails calibration, the potentiometer is likely internally failed.
Repair steps
Power Down
Turn off the tractor and disconnect the battery to prevent electrical shorts during the repair.
Access the Armrest Controls
Remove the secondary control panel/cover on the armrest to access the underside of the remote valve controls.
Remove the Knob
Pull off or unscrew the flow control knob from the top of the 1st remote flow potentiometer.
Remove the Potentiometer
Disconnect the electrical connector from the potentiometer. Remove the retaining nut (3/8-32 thread) securing the potentiometer to the mounting plate, and pull the potentiometer out.
Install the New Part
Insert the new potentiometer, secure it with the retaining nut, and reattach the flow control knob.
Reconnect Power
Reconnect the electrical connector and the tractor's battery.
Calibrate the Remote Valves
Hold the 'PROG' key on the A-post display while turning the ignition key to the ON position. Navigate to the 'ARM' (Armrest) section to find the calibration menu. Follow the on-screen prompts to move the levers (typically pull back, then forward, then to neutral). Turn off the key and wait 30 seconds before starting the tractor to save the calibration.
