The freq valve won't buzz unless the module switches the ground wire on and off many times per second. I applied power and a ground to the valve. It clicked on and off as I applied ground. I can't do it as fast as the module can but yes, it operates. The valve is fine. The red/purple (power wire) has power. The red/brown wire (ground controlled by module) is not grounded. Thus, when I try to read voltage across those wires, I get zero, BUT if I use the engine block as a ground, I read 12 volts DC on red/purple. The ground wire is ok, but the module isn't grounding (read: switching) it. I did a continuity check from the lambda plug to the freq valve and the wire is unbroken. --- In DMCForum@xxxxxxxxxxxxxxx, id <ionicdesign@xxxx> wrote: > did you apply power directly to the freq valve to see if it buzzes? > > cruznmd wrote: > > > Done that already. no joy.
