Hey guys,
I know this isn't really tuning related, but I am getting frustrated here.
Car is a 2017 C7 Z06. Recently out of nowhere, the NPP valves no longer close. This is regardless of what mode the car is in. I tested the wiring to the actuators, and everything checked out good. Good voltage, ground, and good continuity in the signal wire from the chassis control module to the actuators. I replaced the actuators, thinking this was the problem.
Nothing changed, so I replaced the mufflers with some take offs from a friend, but still nothing changed.
I can watch the scanner call for the valves to open and close, depending on what mode the car is in, but the valves themselves do nothing.
Has anyone else ever come across this? Could the chassis control module have gone bad? Any thoughts would be appreciated.
