SOURCE: low oil pressure, stop car on 2001 cadillac seville

HI. this could be a faulty sensor or a bad oil pump screen as well. the oil pump malfunction is the worst scenario in this case. You can actually test the sensor with a voltage needle to see if its getting the proper voltage. i would inspect the wires that are attached to the sensor as well. if the wires are good and the current level is ok as well, it will most likely be a faulty oil pump or bad oil pump screen as well.

In this case, i would recommend inspecting the oil pump assembly. here is a inspection guide below that will help you confirm oil pump failure.

--OIL PUMP INSPECTION GUIDE--

  1. Clean the oil pump components with non-corrosive solvent.
  2. Dry the oil pump components with compressed air.
  3. Inspect the housing and the cover for cracks, scoring, casting imperfections and damaged threads.
  4. Inspect the gerotor gears for chipping, galling or wear.
  5. Inspect the pressure relief valve for embedded particles and/or damage.

The internal parts of the oil pump are not serviced separately. If wear or damage is noted, replace the entire pump assembly.

Please rate and have a great day:)

SOURCE: A light comes on in my car that says oil pressure

If the light is only turning on during acceleration or deceleration and then goes off, this is normal. If the light is constant, and you are sure you have oil that is up to the "full" or "max" level on the dipstick while hot, then it might point to a faulty oil pump or worn gaskets that will no longer prevent the oil from staying in place in the engine. Is this light accompanied by a check engine light. If so what is the code. You may also have a faulty oil sensor. Hope this helps

2004 expedition wants to turn over but wont. Oil pressure low light comes on. Oil level is fine.


The low oil pressure light will come till the vehicle starts an runs ! Explain wants to turn over but won't ? The engine spins over when you turn the key to the start position but won't start an run ? Or when you turn the key to the start position an nothing happens ? If the first one engine spins over but won't start an run , What's missing ? Spark , Fuel pressure , Compression ? Videos on youtube for cranks no start , how to trouble shoot !

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

Low oil pressure on 2006 expedition. stalls going uphill and makes a knocking noise. p0012 and p0340


Check oil flow control valve, camshaft position sensor, crankshaft position sensor and all the wires/ connectors.

Oil light on car won't start


normally i would say if it ran low on oil and now the engine wont turn over, i would suspect internal engine damage. But, have someone check first to be sure it isnt something easy like a battery connection or starter

Engine oil pressure light came on. I checked oil levels and added 1/2 ltr. Light went out and didn't come back on. tune up to be done on Tuesday next week. I suspect it might be the oil filter. Should...


If your oil level is full, light is off and no abnormal engine noises, if should be ok to drive to the shop. If light does come on, stop the engine. I would also have the shop check your oil pressure with a manual gauge, to determine the exact oil pressure reading. This could save you from major engine failure due to low oil pressure. I hope this helps.

My 2006 expedition will not start. the information center says ENGINE:OFF LOW OIL PREESURE....but my oil level is full and clean


If the engine is not running, the low oil pressure indication is correct and normal. There will be no pressure until the engine is actually truning over/running.

How do I check and possibly replace the engine oil pressure sensor in a 2006 GMC Envoy Denali?


Oil Pressure Test Check for proper oil pressure at the sending unit passage with an externally mounted mechanical oil pressure gauge. A tachometer may also be needed, as some specifications may require running the engine at a specific RPM.
  1. While the engine is cold, locate and remove the oil pressure sending unit.
  2. Following the manufacturer's instructions, connect a mechanical oil pressure gauge and, if necessary, a tachometer to the engine.
  3. Start the engine and allow it to idle.
  4. Note and record the oil pressure reading when the engine is cold. The engine may need to run at a specified RPM, if so check the vehicle's specification.
  5. Run the engine until normal operating temperature is reached.
  6. Check the oil pressure reading again with the engine hot and record the value. Turn off the engine.
Compare the hot oil pressure reading to the specification. If the reading is low, check the cold pressure reading against the specification. If the cold pressure is well above the specification, and the hot reading was lower than the specification, the engine may have the wrong viscosity oil. Change the oil, making sure to use the proper grade and quantity, and then repeat the test.
Low oil pressure readings could be attributed to internal component wear, pump related problems, a low oil level, or oil viscosity that is too low. High oil pressure readings could be caused by an overfilled crankcase, too high of an oil viscosity or a faulty pressure relief valve.

Engine oil light is showing on the dash board after switching on


Most important thing you need to do is to establish the actual oil pressure. put a mechanical gauge on the engine and read real oil pressure. If pressure is low (min is 15psi, I prefer to see at least 20 at idle) there is an internal problem...bearings etc. If pressure is good, sending unit has failed...replace it. I would not drive it 'till the oil pressure is verified as being safe. You might get lucky and someone just forgot to plug in the sending unit, but it must be checked!!!
good luck
