P2146: Fuel Injector Group A, Supply Voltage Circuit/Open
The P2146 code is related to the high control circuit of the fuel injector in cylinder 1. The Engine Control Module (ECM) supplies voltage to each fuel injector on the high control circuits. The ECM energizes each fuel injector by grounding the low control circuit of the fuel injector.
When the ECM detects that the fuel injector high voltage supply circuit is not to factory specifications, it disables the affected fuel injector(s).
This results in the Diagnostic Trouble Code (DTC) being set.
