Nissan Micra with Faulty Injector Driver Waveform Notes
The above waveform shows a Nissan Micra with a faulty injector: the injector driver for cylinder number 4 was found to be faulty which meant the injector was not opening.
In this waveform the FirstLook sensor is connected to the fuel pressure regulator and it shows that the fuel pressure on the rail does not drop when injector number 4 is supposed to open.
Thanks to Andrew Clarkson of John Clarkson Auto Services for supplying this waveform.
