The P122A fault code refers to a problem with the control circuit of fuel injector 3 in the engine. The Engine Control Module (ECM) supplies voltage to each fuel injector and monitors their status.

When the ECM detects an issue with the fuel injector circuit, it will disable the affected fuel injectors, potentially disabling the entire group.

The P122A code is set when the ECM injector output driver detects an incorrect current on the fuel injector 3 circuit.

This fault code indicates a problem with the control circuit of fuel injector 3, which may require further diagnosis and repair.
