It will not hurt to drive the vehicle in the short term but I would restrict my driving and be sure to get it fixed as soon as possible.
Here is what I would do as far as testing, Access the injector driver module located in the left front wheel well. Unplug the module and look for any signs of water or corrosion, repair as necessary. With connector unplugged, apply 12 volts to the pins indicated on attached injector circuit diagnostic and ensure that voltage comes back from all the injectors. If any injector circuits show a significant voltage drop, perform the same test at the valve cover gasket, see the attached valve cover gasket test. If it still fails at the valve cover, test the resistance of injector on that circuit. Normal injector resistance is 1.5 to 3.5 ohms. If the injector resistance is out of range, suspect a failed injector coil. If the injector is ok, but the circuit tests fail through the valve cover gasket, replace the gasket and the under valve cover harness. If the test fails at the injector driver module(IDM), but passes at the valve cover gasket, suspect a shorted circuit between the IDM and the valve cover gasket. If all the circuit tests pass, and valve cover gasket, harness, and fuel injector are ok, but the codes continue to set, suspect an IDM issue. Test powers and grounds to the IDM before replacing the IDM
It does not seem like a problem but double checking any connectors in that area would not hurt.
