Oil Pressure Gauge: Description and Operation
Description
DESCRIPTION
An oil pressure gauge is standard equipment on all instrument clusters except for ST vehicles with a gasoline engine. This gauge is located in the upper
right quadrant of the instrument cluster, above the coolant temperature gauge. This gauge consists of a movable gauge needle or pointer controlled by the
instrument cluster circuitry and a fixed 90 degree scale on the cluster overlay that reads left-to-right from L (or Low) to H (or High) for gasoline
engines. On vehicles with a diesel engine the scale reads from 0 kPa to 760 kPa in markets where a metric instrument cluster is specified, or from 0 psi
to 110 psi in all other markets.
An International Control and Display Symbol icon for Engine Oil is located on the cluster overlay, directly below the left end of the gauge scale. The
oil pressure gauge graphics are black against a white field except for a single red graduation at the low end of the gauge scale making them clearly visible
within the instrument cluster in daylight. When illuminated from behind by the panel lamps dimmer controlled cluster general illumination lighting with
the exterior lamps turned ON, the black graphics appear blue-green and the red graphics still appear red. The gauge needle has internal optical
illumination. Gauge illumination is provided by replaceable incandescent bulb and holder units located on the instrument cluster electronic circuit board.
The oil pressure gauge is serviced as a unit with the instrument cluster.
