Recently been having an issue where my gas pedal position signal 2 suddenly looses power then gets it right back(graph on right side). Replaced the pedal and still have that issue. Pulled up the data on an oscilloscope and the signal never dropped out. Tried different scanner and still showed the signal dropping. Is there a chance it can be the ecu itself and that’s what it passed the scope test because the wiring is good but the ecu is dropping the signal?

I fought a throttle pedal issue a few years back,replaced the throttle pedal and throttle body and still had issues with the pedal dropping out,finally found the issue by hooking up a good scan tool and going for a drive,and it would lose signal on bumps,turned out to be a bad pin in the connector at the throttle body,a repair harness from the dealer cured the issue.Not saying it's your issue,but might be something to check,by wiggling the connector at the throttle body
