Function table solenoid valve
If the engine does not run, there is only voltage to the solenoid valves for approximately 3 seconds after the
ignition has been switched to the ON position. This limitation can be bypassed by temporarily disconnect-
ing the cable connector from the engine's oil pressure sensor.
X = The valve in shift function. Y= 1 inlet and 2 outlet.
