Oil pressure warning

We have a 5 week old Outlander and the oil pressure light came on followed shortly by the car cutting out. Is this more likey to be a sensor or an actual pressure problem? If it was actual low pressure, how will I know if the engine is damaged in anyway?

On that new car it is more likely to be the faulty sensor, however if is actual pressure
Problem the only way to find out is by take of the oil pan and investigate the
Connecting rod bearings .
Your car is a new one so you are not allow to do any work on it you must contact
Your dealer immediately and he will check the lubrication pressure with pressure
Gauge to see wheatear it is inside specification or not, if it is not , the warranty system
Will provide you with new engine you do not have to lift a finger .
This is how business is done here in Europe .
I do not know how this works in rest of the world I suspect it is same everywhere

The low oil pressure warning lamp will illuminate anytime the ignition switch is turned to the ON position without the engine running. When the engine is running, the light also illuminates if the engine oil pressure drops below a safe oil pressure level. To test the system, perform the following:
If the oil pressure light does not work, perform the following:
  1. Turn the ignition switch to the ON position.
  2. If the lamp does not light, check for a broken or disconnected wire around the engine and oil pressure sending unit switch.
  3. If the wire at the connector checks out OK, pull the connector loose from the switch and, with a jumper wire, ground the connector to the engine.
  4. With the ignition switch turned to the ON position, check the warning lamp. If the lamp lights, make sure the oil pressure switch is properly grounded in the cylinder block, and if so replace the oil pressure switch. If the lamp still fails to light, check for a burned out lamp or disconnected socket in the instrument cluster.
To diagnose an oil pressure light that stays on, perform the following:
  1. Check the engine oil level and top off as necessary. If the engine was 2 or more quarts low on oil, test start the engine after topping off the oil level and recheck the oil pressure light operation. If the light stays on, stop the engine immediately and go to the next step.
  2. Disconnect the wire at the sending unit, then turn the ignition switch to theON position. If the light remains on, check the wire from the sending unit to the gauge for being shorted to ground and repair as necessary. If the light goes out, turn the ignition switch OFF and go to the next step.
  3. Replace the oil pressure sending switch with a known good switch.
  4. Start the engine and check the oil pressure light operation. If the light stays on with the engine running, stop the engine immediately to avoid severe engine damage until the cause of the problem can be determined.

WARNING
If the oil pressure light remains on while the engine is started, stop the engine immediately. Do not operate the engine until the cause of the problem can be determined. Operating an engine with low oil pressure will cause severe internal damage.

Possible causes for an oil pressure light to stay on are:


Pinched or grounded sensor wireDefective oil pressure sending unitRestricted or severely leaking oil filterExcessive internal engine bearing clearance.Insufficient or severely contaminated engine oilBlocked oil pump pickup screen or severely worn oil pump

Why would the oil light stay on?


That depends on the type of oil warning light being displayed. There are 2 types of warning lights

1. Low oil pressure light which all cars have
2. low oil level light which some cars have.

Low OIL PRESSURE warning means the oil pressure is below minimum and when this happens there will be insufficient lubrication of many engine parts because sufficient oil cannot get to all parts of the engine it is required to lubricate. Until the cause is identified and rectified the warning light will remain. If you run your engine with low oil pressure you will cause expensive damage to internal engine components.

Low OIL LEVEL warning means the oil in the sump has dropped to a dangerously low level (which may be due to an oil leak or abnormal oil consumption by the engine.) This warning means the oil level needs to be topped up and the warning will stay displayed until you top up the oil. Running the engine with low oil will cause expensive engine damage.
Since it is a 2 minute job, Oil levels should be checked fortnightly as a minimum, together with radiator coolant and power steering fluid levels, if you run the car most days each week as most people do.

It is possible for a warning light to remain displayed when the cause has been dealt with because there is a problem with the sender unit. However it needs to be established with alternative checks that the problem has been fixed before investigating if there is a problem with the warning light itself.

Po521 code on a 2010 Camaro ss


Possible causes
- Low oil level or motor mechanical fault
- Faulty oil pressure sensor
- Oil Pressure Sensor harness is open or shorted
- Oil Pressure Sensor circuit poor electrical connection

When is the code detected?
The P0521 is detected when the signal sent from oil pressure sensor to PCM goes out of range.
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Oil pressure warning light ON.
P0521 Chevrolet Description
The PCM continuously monitors the engine oil pressure. The Oil Pressure Sensor/Switch sends a signal to the PCM when the engine is running.

Oil light comes on when starting engine or when excelerating. Started last week, checked level was fine changed oil and filter this weekend and still doing it.


An easy one, finally.
The oil pressure sensor is one of the least reliable parts of any car and yours is bad. They are supposed to turn on the 'idiot light' at ~ 4 pounds of pressure which is almost too late for any warning since oil pressures range from ~30- ~60 pounds in most engines.
These are common failures and not costly to replace. Once you know where it is, with an appropriate wrench, it's about a 5-minute job.

Oil light stays on and oil level is not low


two possible problems

1.) did not reset the oil light after service
2.) short in the oil pressure or temp sensor circuit

either case, seek assistance from your local dealer or service facility

Oil light flickers when in idle. Oil on dip stick measures fine.


install a mechanical guage to test the actual pressure, if its fine the sending unit is faulty, if nor remove the oil pan and check the oil pickup for blockage,

Engine cuts out


Although your pollen filter will not cause the engine to cut out, a lack of oil pressure will. Check your oil level. Then take your vehicle into a dealer soonest.

The oil pressure switch is a short circuit when there is low oil pressure. Removing the wire from it should turn off the warning light. If it doesn't, the chances are there is a short circuit between the lamp and the sensor.

1995 cherokee 2.5 td 150k miles will not start.


The oil pressure dropping to zero is common for cherokees. Replace the oil pressure sending unit and it will be good as new. Cracked exhaust manifolds are also common. Usually it will crack where the 2 pipes are welded into 1 pipe before it connects to the front pipe. There are lots of replacement headers out there to choose from. I just ordered one through quadratec.
