What was the outcome of the vehicle Greg?
Hello Greg and sorry for this late reply. How did you get on with this vehicle regarding code P1222? I have experienced a number of issues surrounding gas pedal position sensors where I have struggled to prove a pedal failure given I have acquired similar scope patterns to the one you have posted. I don't think there is an issue with the maximum output, it appears more the relationship between the sensor outputs as the voltages should mirror one another separated by a specified value. When I look at the section of the waveform where you have pressed the gas pedal numerous times Channel A rise and fall appears consistent whereas the fall in voltage of channel B (returning to the rest position) appears to wander.
