Description:

This diagnostic trouble code indicates that the circuit current for the EGR valve actuator is too low, pointing to an open circuit within the system.

Reaction:

The control software may disable the EGR valve operation to prevent erratic behavior or potential damage due to inadequate actuator control.

Recommendations:

• Inspect Wiring and Connectors: Check all associated wiring and connectors for breaks, disconnections, or other signs of an open circuit.
• Test Actuator Operation: Use a multimeter to measure the current flow to the actuator. Verify against manufacturer specifications to confirm if the current is indeed too low.
• Replace Faulty Components: Repair or replace any faulty wiring, connectors, or the actuator itself if it fails to draw adequate current.
• Reset ECU and Functional Test: After repairs, reset the ECU to ensure it recognizes the corrected state. Test the EGR system to verify that the actuator operates correctly.

Note:

Ensuring that the EGR valve actuator receives proper current is essential for maintaining accurate control over the EGR system and supporting efficient engine operation and emissions compliance.
