Solenoid Valves (Shift Solenoid-A, Shift 
Solenoid-B, Shift Solenoid-E, TCC Solenoid, 
Pressure Control Solenoid-A, Pressure Control 
Solenoid-B, and Pressure Control Solenoid-C) 
Inspection

S6JB0B5106022

Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B 
and Shift Solenoid-E)
Resistance check

CAUTION

!

 

Be very careful as dust etc. does not enter 
when solenoid valves are inspected.

 

Measure resistance between terminal (2) and solenoid 
valve body. If resistance is out of specification, replace 
solenoid valve.

Shift solenoid-A, Shift solenoid-B and Shift solenoid-
E resistance
Standard: 11 – 15 

Ω (at 20 °C (68 °F))

Operation Check
• With solenoid connected to battery (2) as shown in the 

figure, check that solenoid valve is actuated with click 
sound.

• With shift solenoid valve (1) connected to battery (2), 

confirm that shift solenoid valve is open by blowing air 
(50 – 200 kPa, 0.5 – 2.0 kg/cm

2

, 7 – 28.5 psi) into 

solenoid valve as shown in the figure.

• With shift solenoid valve (1) not connected to battery 

(2), confirm that shift solenoid valve is closed by 
blowing air (50 – 200 kPa, 0.5 – 2.0 kg/cm

2

, 7 – 28.5 

psi) into solenoid valve as shown in the figure.

CAUTION

!

 

Do not insert air gun against strainer 
installed on inlet of solenoid valve too deeply, 
when blowing air into solenoid valve. If not, 
the strainer will be damaged.

Resistance check

CAUTION

!

 

Be very careful as dust etc. does not enter 
when pressure control solenoid valves are 
inspected.

 

Measure resistance between pressure control solenoid 
valves (Pressure control solenoid-A, Pressure control 
solenoid-B, Pressure control solenoid-C and TCC 
solenoid) (1) terminals. If resistance is out of 
specification, replace valve body assembly.

Pressure control solenoid-A, Pressure control 
solenoid-B, Pressure control solenoid-C and TCC 
solenoid resistance
Standard: 5.0 – 5.6 

Ω (at 20 °C (68 °F))

Operation check
Check pressure control solenoid valves (Pressure 
control solenoid-A, Pressure control solenoid-B, 
Pressure control solenoid-C and TCC solenoid) (1) 
operation in either of the following methods.
[Using regulated DC power supply]

1) Connect pressure control solenoid valve (1) with 

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 that valve (3) moves gradually in arrow “A” 

direction as voltage increases.

4) Check that valve (3) moves in arrow “B” direction as 

voltage decreases.

5) Turn power supply switch OFF.

CAUTION

!

 

Do not feed current 1.0 A or more, or 
pressure control solenoid will be burned out.

 

[Not using regulated DC power supply]

1) Connect pressure control solenoid valve (1) to 

battery (4) setting 21 W bulb (2) in between as 
shown in the figure.

2) Check that valve (3) moves in arrow “A” direction.
3) Disconnect pressure control solenoid valve (1) from 

battery (4) and check that valve (3) moves in arrow 
“B” direction as shown in the figure.

CAUTION

!

 

Set 21 W bulb in between, or pressure control 
solenoid valve will be burned out.
