P240A 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 diagnostic code is stored if the current consumption of the pump in the leak detection pump unit varies too much during the reference phase.
