Vacuum Switch Inspection
1) Disconnect coupler from vacuum switch and check resistance between two terminals of vacuum switch.
If resistance is out of specification, replace.
Resistance of vacuum switch
More than 1 MΩ
2) Connect vacuum pump gauge and apply vacuum more than –40 kPa (–5.70 psi), then check resistance between terminals of vacuum switch.
If resistance is out of specification, replace.
Vacuum switch resistance
Less than 0.8 Ω
