What does P0202 Cylinder 2 Injector Circuit Open mean on vauxhall vectra b?
Wiki User

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.
