Common Diagnostic Steps

OBD2 Code: P1441

Description: Mini Leakage Diagnostic Pump Control Open Circuit

Check the vehicle’s battery voltage and ensure it is within the specified range.
Inspect the wiring and connectors related to the leakage diagnostic pump for any signs of damage, corrosion, or disconnection.
Test the leakage diagnostic pump relay for proper operation and replace if necessary.
Use a multimeter to check for continuity in the circuit between the engine control module (ECM) and the leakage diagnostic pump.
Verify that there are no blown fuses associated with the leakage diagnostic pump circuit.
If applicable, use a scan tool to activate the leakage diagnostic pump and listen for its operation. Replace if non-functional.
Examine ECM connections for any loose pins or poor contact points that could affect communication with the pump.
If all other components test fine, consider replacing the leakage diagnostic pump itself as a last resort.
