70 Instruments and Controls
C — Engine Oil Pressure
The gauge indicates oil pressure by a sensor
directly connected to the engine lubrication
system. Normal oil pressure is 30 to 70 psi
(210 to 480 kPa) when the engine is at nor-
mal operating temperature. At idle speed,
the pressure may drop to 5 to 20 psi (35 to
140 kPa). When first starting a cold engine,
oil pressure may exceed 90 psi (620 kPa).
The LED light in the lower right corner of
the gauge lights up solid when the oil pres-
sure is too low. The pressure limit is
dependent on the engine manufacturer elec-
tronic program. When the gauge light
comes on, the red
1
STOP telltale starts
blinking, the buzzer sounds and the oil
pressure symbol appears on the graphic dis-
play. The engine is at risk and the engine
controller may react by derating the engine
power, for example. Bring the vehicle to a
safe stop where the problem can be
checked.
With very low oil pressure, the red
1
STOP
telltale lights up solid. The engine will shut
down within 30 seconds from when the
light came on. Pull off the road as soon as
possible without being a safety hazard.
Failure to take necessary action when
the
1
STOP telltale is on, can ultimately
result in automatic engine shutdown and
loss of power steering assist. Vehicle
crash resulting in personal injury or
death can occur.
