ICC 003352.07 – Engine Exhaust Pressure Regulator Vent Valve Position Not Responding or Out of Adjustment

ICC 003352.07 (ICC 3352.07)

Code: 003352.07

Shortcode: 3352.07


This code indicates that the Hybrid Exhaust Actuator is not able to reach the intended position, suggesting that the Engine Exhaust Pressure Regulator Vent Valve position is either not responding or out of adjustment. This can be caused by mechanical issues, sensor problems, or faults in the actuator control system.


The exhaust pressure regulation may not function properly, potentially leading to increased emissions, reduced engine performance, and potential damage to the exhaust system. The operator might see a warning light or message on the dashboard.


  • Inspect Actuator and Valve:
    • Check the hybrid exhaust actuator and vent valve for proper operation. Ensure that they move freely and are not obstructed.
    • Replace the actuator or valve if they are found to be defective.
  • Examine Wiring and Connectors:
    • Inspect the wiring harness and connectors associated with the actuator and valve for signs of damage, corrosion, or loose connections.
    • Repair or replace any damaged components.
  • Test Control System:
    • Use diagnostic tools to verify the functionality of the control system managing the actuator and valve.
    • Update the control system software to the latest version.
  • Calibrate Actuator and Valve:
    • Perform a calibration procedure using diagnostic tools to ensure the actuator and valve are properly adjusted.


Regular maintenance and calibration of the exhaust system components can help prevent issues and ensure optimal performance.
