New Holland EHR 4326 – EHR (Electro-Hydraulic Remote) Control Module: Rear Remote No.7 -Position Transducer Faulty

This code indicates that the position sensor (transducer) monitoring the spool movement for the #7 rear hydraulic remote valve is sending an erratic, out-of-range, or missing signal. Because of this, the system cannot determine the physical position of the #7 remote valve spool, which will typically disable the remote or prevent it from returning to neutral properly.

1. 1

   Visual Inspection: Inspect the wiring harness and connector at the #7 rear remote valve slice. Look for broken wires, corrosion, or pushed-out pins.

2. 2

   Voltage Test: Disconnect the sensor and turn the key ON. Verify that the sensor is receiving the proper 5V reference signal and has a good ground from the EHR controller.

3. 3

   Component Swap Test: Swap the position transducer from the #7 remote with a known good transducer from an adjacent remote (such as remote #6 or #8). If the fault code changes to follow the sensor (e.g., throwing EHR 4329/4330 for remote #8), the transducer itself is internally failed. If EHR 4326 remains active, the issue is in the tractor's wiring harness or the EHR controller.

1. 1

   Prepare machine

   Park the tractor on a level surface, lower all implements, turn off the engine, and relieve all hydraulic system pressure.

2. 2

   Locate valve

   Locate the #7 rear remote valve slice at the rear hydraulic block.

3. 3

   Disconnect harness

   Disconnect the electrical harness connector from the faulty position transducer.

4. 4

   Remove transducer

   Unbolt and carefully remove the position transducer from the valve body.

5. 5

   Install new transducer

   Install the new position transducer, ensuring the mechanical linkage/pin aligns correctly with the valve spool. Torque the mounting bolts to OEM specifications.

6. 6

   Reconnect harness

   Reconnect the electrical harness.

7. 7

   Perform calibration

   Power on the tractor and use the in-cab display monitor (or a dealer electronic service tool) to perform a hydraulic remote valve calibration. This step is mandatory so the EHR controller can learn the new sensor's exact neutral, full-extend, and full-retract voltage values.
