Oil Temperature and Oil Pressure
Switches
The oil temperature switch is a normally open
switch that closes at approximately 220° F
(104° C). When the switch closes, the engine will
shut off to prevent damage and will not start until
the temperature drops below the switch point. An
over-temperature indicator light at the ground
controls should turn on when the switch closes.
Component damage hazard.
Do not crank the engine with
the over-temperature light on.
The oil pressure switch is a normally closed switch
that opens at approximately 15 psi (1 bar). If the oil
pressure drops below the switch point, the switch
opens and shuts off the engine to prevent damage.
A low oil pressure indicator light at the ground
controls should turn on when the switch opens.
Component damage hazard.
Do not crank the engine with the
low oil pressure light on.
