First post and new user to torque but I’m
confused about something and have a question.
I have a 1997 civic auto bone stock. I have a
issue with the fuel system status, when I’m driving
and I let off the gas pedal the fuel system status
changes from closed loop to “unassigned value (7)”.
It changes back to closed loop when back on the gas,
and when at 75% throttle or higher the same thing happens
the car goes back into unassigned value (7) and closed
loop once you let off the throttle.

The car with start and warm up in open loop and go to
closed loop once warmed up.

What is unassigned value (7)? Anybody else seen this before
