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
1STOP 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.
