Oil Pressure Gauge: Testing and Inspection
Oil Pressure Gauge Test
If the problem being diagnosed is related to oil pressure gauge accuracy, be certain to confirm that the problem is with the gauge and not with the engine
oiling system performance. The actual engine oil pressure should be checked with a test gauge and compared to the instrument cluster oil pressure gauge
readings before you proceed with gauge diagnosis.
WARNING: ON VEHICLES EQUIPPED WITH AIR-BAGS, REFER TO AIRBAG SYSTEMS BEFORE ATTEMPTING ANY STEERING
WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE
PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
Diagnosis of the oil pressure sensor and circuit, the Chrysler Collision Detection (CCD) data bus, and/or the Powertrain Control Module (PCM) should
be performed with a DRB scan tool. For further diagnosis of the oil pressure gauge and the instrument cluster circuitry, see Instrument Panel, Gauges and
Warning Indicators/Instrument Panel/Instrument Cluster.
