Hello Expeerminter (Can I have your name please?
I have some waveforms from a differential pressure sensor, that I captured, whilst applying a vacuum & then pressure. I have never bothered capturing the signal from the temperature sensors though. They don't seem to give any problems.
I find it more convenient to study the pressure readings vie serial data. By observing the pressure reading at "key on engine off" & then running the engine at a variety of speeds, it is possible to determine if the sensor is functioning correctly & furthermore, if the DPF is clogged, partially clogged, or even clear. Some back pressure is necessary, otherwise a DTC will be set for "Particulate filter punctured"
