DTC 100 Oil Pressure Low/High/High at Stall
Conditions for Setting the DTC
The normal voltage output limits for this sensor are 0.5 volts to 4.5 volts. If at any time, the voltage output
is less than 0.46 volts or greater than 4.54 volts a DTC will be triggered. If the engine is not rotating the oil
pressure should not raise above 0 psig. Due to the nature of this sensor an open ground wire with Key ON
engine off may result in the signal voltage drifting up above 1 volt even at 0 psig oil pressure. To sense
this fault a diagnostic is triggered if at an engine speed of 0 rpm the sensor voltage is above 1.0 volts.
Circuit Description
The engine has an internal oil pump which creates oil pressure once the engine is rotating. An oil pressure
sensor monitors the pressure created by this oil pump.
