now that helps me get me head round the wording of the fault code, as im reasonable confident that I know how the sensor works...when I first tried scoping it I couldn't understand what I was looking at, as the trace of an analogue voltage and the trace of the varying frequency of the digital signal are similar, and it took a while to understand what I was seeing ..I did think the reason for fitting a digital sensor was to save the ecu job of converting...

The mass air flow can be used as a feedback or verification of a working egr system.. When the egr is working there should be a corresponding reduction in mass air flowing as the recycled exhaust gas makes up part of the charge in the cylinder👍
That's if you have a working egr system🤔😂 I'm going to do a bit more on the vcv and fuel rail pressures when I get round to it.. In the hope that a given output will have a bearing on rail pressure.. I tried it a while back but without having a load on the engine the vcv duty cycle was tiny And barely noticeable even when the engine was revved |
