Oil Pressure Gauge: Description and Operation
Oil Pressure Gauge - Description
DESCRIPTION
An oil pressure indicator is found only in the instrument cluster of SRT8 vehicles. The oil pressure indicator is an additional function of the Electronic
Vehicle Information Center (EVIC) and is selected using the STEP button in the upper instrument panel switch pod while in the trip computer mode.
This indication appears within the reconfigurable dot matrix Organic Light Emitting Diode (OLED) display unit.
The oil pressure indicator consists of an International Control and Display Symbol icon for Engine Oil, a gauge bar, and an alpha/numeric display of the
current oil pressure in either KPA (kilo Pascals) or PSI (Pounds/Square Inch), as selected with the U.S./METRIC feature of the EVIC. The indicator
displays values from 0 to 750 kPa, or from 0 to 100 psi. The oil pressure indicator appears in place of the compass/trip computer information in the dot
matrix display.
The dot matrix OLED is soldered onto the cluster electronic circuit board, and is visible through a window with a smoked clear lens located on the lower
edge of the tachometer gauge dial face of the cluster overlay. The dark lens over the OLED prevents the indicator from being clearly visible when it is
not illuminated. The oil pressure indicator appears in the same white color and at the same lighting level as the compass/trip computer information when
it is illuminated by the instrument cluster electronic circuit board.
The oil pressure indicator is serviced as a unit with the OLED in the instrument cluster.
