Code P1447 MINI Description
During the Reference Leak Measurement, the electrically actuated pump delivers through the reference restriction. The engine-management system measures the pump's electrical current consumption in this section.
During the Leak Measurement, the electrically actuated pump delivers through the charcoal canister into the fuel-tank system. The pressure in the evaporative system may be up to 2.5 kPa depending on the fuel level in the tank. The engine-management system measures the pump's electrical current consumption. A comparison of the currents of the reference leak measurement and the leak measurement is an indication of the leakage in the tank.
What are the Possible Causes of the DTC P1447 MINI?
- Faulty Diagnostic Module Tank Leakage (DMTL) Pump
- Diagnostic Module Tank Leakage Pump harness is open or shorted
- Diagnostic Module Tank Leakage Pump circuit poor electrical connection
