[2] AUX SOLENOID VALVE

(1) Specifications

Proportional Control Solenoid Valve
This valve is an electromagnetic solenoid valve. Normally a solenoid valve is turned off and on via 12V battery
voltage, but this valve is controlled via pulsed signals from the computer built into the ECU and the meter panel.
