(14) Oil Pressure Sensor (DTC 524)
DTC 524-Oil Pressure Low
• Hardware: Engine Oil Pressure Sensor or Switch
• Enabling Conditions: Key on, Engine Running longer than 15 seconds and running higher than 1300 min
-1
(rpm)
• Set Conditions: Engine oil pressure switch circuit < 2.50 V for longer than 3 seconds
• Corrective Action(s): Illuminate MIL and initiate an engine shutdown
• Non-emissions related fault
• Possible Causes: Oil pressure problem with engine, oil pressure switch failure, oil pressure switch circuit shorted
to ground, faulty ECM
The ECM can be configured to monitor oil pressure through a switch. Oil pressure monitoring is important to
prevent engine damage due to low oil pressure resulting in higher friction and lack of lubrication. In addition, high oil
pressure can be undesirable because it can cause oil to leak past seals and rings, can be a result of a restriction in
the oil flow path, or can be a sign of a malfunctioning oiling system.
If the switch is normally open, the fault will set if the circuit becomes grounded. Go to the Faults page in EDIS to
determine how the input is configured. ("Open=OK" is normally open). The engine will should be configured to derate
or force idle and/or shut down in the event of this fault to help prevent possible damage.
