The P2156 code is related to the fuel injector circuit in the engine. It indicates that the high control circuit of the fuel injector in cylinder 4 is experiencing low voltage.
The Engine Control Module (ECM) monitors the fuel injector circuits and disables the affected fuel injector(s) when a circuit condition is detected. The DTC is set when the ECM detects that the fuel injector high voltage supply circuit is shorted to ground for more than 2 seconds. This fault code can cause issues with the fuel injection system and may result in poor engine performance or stalling.
