The fuel injectors are not hard to get at on this engine so I do not see the relevancy of this comment. You can even connect a noid light to check the fuel injector pulse width modulation signal. Also, you can run a resistance check of the fuel injector coil. 11-12 ohms.
The best thing to do is check for the 12 volts at the respective injector electrical connector. Ignition to ON. And then connect a noid light or a multimeter and check the injector pulse from the PCM module while engine is running. It will pulse high then low, etc.
This DTC is normally related to an internal PCM module fault related to the output driver module similar to the old quad driver faults on older odb vehicles so the PCM module is a possibility.
