Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P045500

Condition




Engine control module (ECM) checks sealing in the fuel tank system by, using the leakage diagnostics unit, pressurizing the tank system and at the same time monitor the pressure build-up. The pressure is a calculated pressure, calculated using measured power consumption on the pump.
If the pressure is stabilized and/or does not reach over 1500 Pa within 450 seconds, it is interpreted as a leakage bigger than 1.0 mm in diameter from the fuel tank system. Diagnostic trouble code for major leakage stored.
For more information, see Design and Function.
The diagnostic trouble code can be diagnosed when leakage diagnosis is running.
