1C-32 Engine Electrical Devices: For Diesel Engine Model
Boost Pressure Control Solenoid Valve
Inspection
1) Remove boost pressure control solenoid valve
referring to "Boost Pressure Control Solenoid Valve
Removal and Installation: For Diesel Engine Model".
2) Check the resistance between terminals of boost
pressure control solenoid valve is within
specification.
If resistance is not as specified, replace boost
pressure control solenoid valve.
Boost pressure control solenoid valve resistance
14.7 – 16.1 Ω at 20 °C, 68 °F
3) Using special tool, check operation of boost
pressure solenoid valve as follows.
Special tool
(A): 09917–47011
a) Check if vacuum is applied at nozzle "a" with
nozzle "b" blocked off.
If vacuum is applied, replace solenoid valve.
b) Connect battery to solenoid valve as shown in
figure.
In this state, check if vacuum is applied up to 40
kPa (0.4 kg/cm
2
, 5.7 psi) in the same manner as
step a).
If applied vacuum is lower than specified value,
replace solenoid valve.
NOTE
• It is necessary to pump lever of special
S6JB0A1326030
tool several times quickly in order to
increase vacuum up to specified value.
• Valve does not hold vacuum but it does not
indicate anything faulty.
