Technical Notes

If only one fuel injector control circuit Diagnostic Trouble Code (DTC) is set, an open circuit or poor connection is the most likely cause. If groups of 4 fuel injector control circuit DTCs are set, suspect a short to ground. Cylinder groups are 2, 3, 5, 8 or 1, 4, 6, 7. More than 4 fuel injector control circuit DTCs set indicate a short in the fuel injector control circuit is the most likely cause.

Possible Symptoms

  • Engine Light On (or Service Engine Soon Warning Light)
  • Engine misfire
  • Rough running

P1244 CHEVROLET Meaning

The Engine Control Module (ECM) activates the appropriate fuel injector on the compression stroke for each cylinder. The ECM controls the Fuel Injection Control Module (FICM) by grounding the control circuit through a semiconductor device called a driver. The ECM monitors the driver status. If the ECM detects an incorrect voltage for the commanded state of a fuel injector driver, Diagnostic Trouble Code (DTC) P1223, P1226, P1229, P1232, P1235, P1238, P1241 or P1244 will be set.
