Engine Oil Pressure
Gauge
Metric
English
The oil pressure gauge shows the
engine oil pressure in psi (pounds
per square inch) when the engine is
running. Canadian vehicles indicate
pressure in kPa (kilopascals).
The oil pressure gauge will read
zero when operating in the AUTO
STOP mode.
Oil pressure should be 200 to
550 kPa (29 to 80 psi). In certain
situations, such as long extended
idles on hot days, it could read as
low as 105 kPa (15 psi) and still be
considered normal.
Black plate (6,1)
When the engine is running,
readings in the low pressure zone
may be caused by a dangerously
low oil level or some other problem
causing low oil pressure. Check the
oil as soon a possible.
WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
