Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P045500

Condition




The engine control module (ECM) checks for leaks in the fuel system by measuring the current consumption of the leakage diagnosis pump when pressure is applied.
If the current consumption measured under pressure does not change in a specific way or a certain pressure is not obtained in the system within a reasonable amount of time, the control module assesses this as a large leak (leak larger than 1.0 mm) from the fuel system. See Design and Function for more information.
The diagnostic trouble code can be diagnosed when leakage diagnosis is running.
