The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosing and fixing the P2148 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.
P2148: Fuel Injector Group A Supply Voltage Circuit/Open
The P2148 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 shorted to voltage for more than 2 seconds, it disables the affected fuel injector(s).
This condition triggers the Diagnostic Trouble Code (DTC) and sets the P2148 code.
