P0202 relates to the fuel injector on cylinder No2.
The code SUGGESTS that the injector has no electrical power to it.
These work on a constant 12V feed and the ground is supplied by the ECU by a predetermined map.
i.e. open circuit = no complete electrical circuit.
The most effective way of checking this is with an oscilloscope.
A multi meter may not capture the power at the correct time due to the slow refresh rate.
