Volunteer needed: VIAS solenoid identification
 

Looking for a volunteer with a code reader to identify which VIAS solenoid is which. There are two separate solenoids which engage at different setpoints (operate 2 separate valves in the manifold.)

I need this volunteer to un-plug one solenoid, go for a short drive if necessary, and scan for reported trouble codes. It will be either P1800 or P1801. Note, the CEL will not illuminate as it is a "ghost" code.

Why? I have a seventh gen motor in my 03 Maxima and want to run my solenoids separately for maximum torque benefit. Currently mine are tied together which isn't ideal. I've done some mods to my ECU to run them separately, but don't know which is which.
