P0524 Engine Oil Pressure Too Low
Check engine lightOn
EmissionsNot relevant
Drive cycleRequired
Limp modePossible
P0524 is not a sensor fault but a condition: the measured oil pressure is below a minimum depending on speed, load and temperature (Ford diesel 30–90 kPa) for about 5 s, with the sensor itself plausible. Its purpose is engine protection; Ford petrol engines with mid-lock cam phasers drive them into the locked position. GM's tables do not use it; FCA updated the Ram EcoDiesel software against false setting in the cold. Stop the engine, check the oil level and confirm with a mechanical gauge.
Likely causes
Oil level too low, oil loss or consumption
Too thin oil, fuel dilution or clogged pick-up screen
Oil pump or pressure control valve faulty or stuck
Worn crankshaft or camshaft bearings
False setting by software in the cold (Ram EcoDiesel)
Symptoms
- Oil pressure warning and/or check engine light
- Engine noise (lifters, timing chain)
- Possible power reduction
