    Code fault 4322:Loss of engine speedy sensor

    • Hello,

      It seems like you are experiencing an issue with your JLG equipment involving the Perkins engine not starting, and you have a fault code 4322 which indicates "Loss of engine speedy sensor." Here are some steps you can take to troubleshoot the issue:

      Inspect the engine speed sensor: Locate the engine speed sensor, which is typically mounted on the engine flywheel housing. Check for any visible damage, corrosion, or loose connections. If you find any issues, clean the connections or replace the damaged parts as needed.

      Check the wiring and connections: Inspect the wiring leading to the engine speed sensor for any damage, wear, or corrosion. Ensure that all connections are secure and in good condition. Repair or replace any damaged wiring or connectors as necessary.

      Test the engine speed sensor: If the sensor and wiring appear to be in good condition, you may need to test the functionality of the engine speed sensor. You can use a digital multimeter to measure the resistance across the sensor terminals (refer to your equipment's service manual for the correct specifications). If the sensor's resistance is out of the specified range, replace the sensor.

      Check the engine control module (ECM): If the sensor and wiring are in good condition, but the problem persists, the issue may lie within the engine control module. Consult a professional technician or your equipment's service manual for guidance on testing and potentially replacing the ECM.

      Refer to the service manual: For further information on troubleshooting the issue, consult your equipment's service manual, which should provide more detailed instructions and specifications related to your specific model.

      If you continue to have issues after following these steps, it is recommended to contact a qualified technician or your JLG equipment dealer for further assistance. Remember to always prioritize safety and follow the manufacturer's guidelines when working with heavy equipment.

      I hope this helps you resolve the issue with your Perkins engine. Good luck!
