Code P0283 2015 Chevrolet Silverado Description

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. The ECM monitors the status of the fuel injector circuits. When a fuel injector circuit condition is detected by the ECM, the affected fuel injector(s) is disabled. The Diagnostic Trouble Code (DTC) will be set when the ECM detects the fuel injector control circuit is shorted to voltage for greater than 2 s.
