DTC code P0205 OBD2 means that there is a problem detected by the Powertrain Control Module (PCM) and the fault is in an injector or even in its wiring.
The Powertrain Control Module (PCM) constantly monitors the injector. When this is activated, the PCM expects to see an approximate voltage of zero or low, and when the injector is deactivated the voltage the PCM expects should be high or close to the battery voltage. In case the PCM does not see the expected voltage, diagnostic code P0205 is set. Equally, this DTC code can be established if there is a problem in the resistance of the injector circuit, if this is high or low in excess is established.
