CHECKING THE OIL PRESSURE
SWITCH CONTINUITY
Check:
• Oil pressure switch continuity
Out of specification → Replace.
Measuring steps
(1) Remove the oil pressure switch.
(2) Connect the mity vac as shown.
(3) Slowly operate the mity vac.
(4) Measure the continuity when the speci-
fied pressure is reached.
