I see it seems to pop through the instrument cluster, then through underbonnet fuse box then onto the ECU.
Would these other components cause the track 2 voltage to drop out? The 5volts remains constant for the tracks, and I'm measuring at the pedal. I could understand it happening if I were testing at the ECU??
I'm obviously missing something here. Now starting to think the drop out isn't causing the fault and is normal!
can't see the waveform right now, i am on my phone. I have seen specific frequency pulses on a gm etc signal for either the tps 2 or app 2 signal line and it is normal and part of the system. for diagnostic purposes. not sure if that applies here.
