P240B Meaning
The engine control module (ECM) monitors the power consumption of the leak detection pump. This diagnostic trouble code (DTC) can be diagnosed when the leak diagnostic system is running. A DTC is stored if the actual current consumption of the pump in the leak detection pump unit varies too much during the reference phase.
