Pressure Control Solenoid Valve Inspection
Reference: Pressure Control Solenoid Valve Removal and Installation
Resistance Check
CAUTION:
Be very careful as dust etc. does enter when pressure control solenoid valve is inspected.
Measure resistance between pressure control solenoid valve (1) terminals.
Pressure control solenoid valve resistance
Standard: 5.0 – 5.6 Ω (at 20 °C (68 °F))
Operation Check
Check pressure control solenoid valve operation in the either manner of the followings.
Using regulated DC power supply
1) Connect pressure control solenoid valve (1) to regulated DC power supply (2) as shown in the figure.
2) Turn regulated DC power supply switch ON, increase voltage of power supply keeping current within 1.0 A.
3) Check for gradual movement of valve (3) in the direction of arrow “A” as voltage is increased.
4) Check for movement of valve (3) in the direction of arrow “B” as voltage is decreased.
5) Turn power supply switch OFF.
CAUTION:
Do not pass current 1.0 A or more, or pressure control solenoid is burned out.
Not using regulated DC power supply
1) Connect pressure control solenoid valve (1) to battery (2) setting the 21 W bulb (4) on the way as shown in the figure.
2) Check for movement of valve (3) in the direction of arrow “A”.
3) Disconnect pressure control solenoid valve (1) from battery (2) and check for movement of valve (3) in the direction of arrow “B” as shown in the figure.
CAUTION:
Set 21 W bulb on the way, or pressure control solenoid valve is burned out.
