Oil Pressure Gauge: Description and Operation
Description
DESCRIPTION
An oil pressure gauge is standard equipment on all instrument clusters. 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.
