DTC P1283 meaning

DTC P1283 refers to a diagnostic trouble code indicating a high to low side open circuit condition in the cylinder #7 fuel injector. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various components of the vehicle’s engine and emissions systems. When the Engine Control Module (ECM) detects that the voltage signal for the fuel injector is not within the expected range, it triggers this code.
