Engine Oil Pressure Switch Continuity
1. Measure the resistance with an ohmmeter across the switch
terminal and the chassis.
2. If 0 ohm is not indicated in the normal state, the switch is faulty.
3. If infinity is not indicated at pressure over 4.9 kPa (0.5 kgf/cm
2
, 7
psi), the switch is faulty.
