Nothing in the smog check manual indicates a vehicle can not be smog checked if the transmission is mising the reverse gear or if reverse is not working, but there is the matter of the illuminated malfuncition indicator lamp. Your Honda Civic can not pass the smog check with its MIL light ON, even if the code is for the CVT Drive Pully Speed Sensor Circuit. The ARB has identifed this fault as to affect emissions; as such, it is a smog check failure. You will need to fix the CVT problem and then have your Honda Civic smog tested.
