    I don,t know where you may find any examples,but with a scope the wave will look similar to an injector as the solenoid cycles.These can be very hard to make heads or tails of as the sol. is usually on or off and not cycleing.In the case of a Chrysler product ,for example ,if you are scoping a sol. while the computer is running a self test ,the time involved will be very fast and takes a very good scope to catch it.

    If you are graphing with a scan tool,what you are going to see in most cases is an on/off command from the PCM and this will not tell you if the solenoid actually worked or not,just that it was commanded to work.
