Measure voltage across the connector with ignition on should be +12V if lower here indicates earth fault which is switched by ecu (Could just be poor wiring) if this is good would suspect a faulty valve.
I'm not sure on your car but can't see any reason why a amal can't be used unless different electronics/resistance.
