Oil warning light on -- oil level in sump okay What solution

yes on some models when you change the oil then the filter you need to add oil to the new filter then put it on see the system has to build up a prime and some motors are weak and cannot pick the new oil up Good Luck let me know Mike L.

Keith, it probably is the oil pressure light.

Low oil level causes low oil pressure. But, as you say .. your oil level is okay. It may be the oil pressure sender which is at fault. There's every possibility that your oil pressure is fine, but the sender is sending a false signal to your dashboard which gives the 'low oil level' warning light.

Get the mechanic at your local dealership to stick his head under the hood. You'll get a diagnosis in seconds. I don't think you have too much to worry about .. just that 'low oil level' warning light is a bit unsettling ..

If you have a yellow oil pressure warning light displaying then you may have 2 problems
1. Your oil level is way too low and needs topping up which very often means you are a sloppy owner that does not bother to regularly check the oil level in the engine and probably the other fluids as well.

2. There is a problem with the oil pressure and it is below the minimum needed to lubricate the engine.

What you need to do:

1. Check the oil level and top it up to the max level with the correct grade and type of oil as specified by Toyota for that engine.
Do not overfill the sump.
2. Check to see if the oil pressure warning is continuing to display when the sump has been filled to the correct level. If you still have the oil pressure warning you need to have it investigated and the cause of the low pressure rectified otherwise you will destroy your engine if you continue to run it with less than minimum pressure. A mechanic needs in the first place to connect an independent oil pressure gauge to the engine to check the actual pressure readings. This will also eliminate any possibility that there is an issue with the oil pressure sensor and sender unit (which is not likely). .

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.

You have to find the source f the problem as to why it went off in the first place. Oil sensor garage is part of a service interval that you should be getting. if you have gotten your service already check the oil level in your car if its to low it will stay on. If you hundred percent sure the oil level is correct by checking your dipstick then try resetting it by going to your fuse box and taking out fuses nr 11 and 15 leave it out for a minute at least then put them back. if it still shows on it could be the sensor inside the sump that needs to be replaced

1) Purchase appropriate oil filter, sump drain bung washer and chosen engine oil.
2) Prepare an oil pan, sump bung wrench and oil filter removal tool (check access to oil filter to be sure that your tool is suitable.)
3) Run the engine until its warm to hot.
4) With the car jacked up and secured, remove engine oil filler cap and remove engine oil sump drain bung and allow oil to flow out into your drain pan. Keep an eye on your oil and make sure it doesn't overflow from your drain pan.

5) Refit sump bung with new washer and tighten. Do not over-tighten, and be especially careful when tightening into an alluminium sump.


6) Remove oil filter. Oil will flow out from this filter when removing, so your drain pan will need to be under the filter housing when removing.


7) Run a smear of clean engine oil around the filter rubber seal and refit new filter. Tighten hand tight only. Do NOT crank this filter super tight as you may damage the rubber seal and even the filter casing which can impede oil flow.


8) Refill engine with proper quantity of oil. If you cannot find how much oil your engine is supposed to take, then refill with the same quantity of oil which you drained out.


9) Restart the engine while checking the oil pressure warning light on the dash. The warning light may stay on for three or four seconds and then go out. If this light stays on for longer, then stop your engine and check for oil leaks at the filter body and sump drain bung.


10) Once the engine oil pressure warning light is off after starting, stop the engine and check the engine oil level (with vehicle on the flat and off any axle stands.)


11) Road test the vehicle, driving it for a mile or two before re-checking for oil leaks under the engine bay and engine oil quantity.

Better off replacing the sump gasket and sump plug washer before travelling. Working in public health I have seen many motor cycle accidents caused by oil patches on roads esspecially after rain.

The oil pressure sender unit is located on the oil filter housing.These do tend to leak at times. The warning light for this switch is a red oil can and a buzzer. Replace the switch. If warning light still comes on, have the oil pressure checked. The oil level sender warning light is an orange oil can with oil level under it. This sender is fitted on the bottom of the oil sump and can leak past the seal. If warning light comes on, check oil level. If ok, check for damage to wiring under vehicle. Senders do some times become faulty.

Incorrect level. Check level at operating temps and while the engine is running. By sump and stainer you meant that you removed the oil pan off the car and cleaned the pickup tube of the oil pump? I'd suggest hooking up an oil pressure gauge so you'll know which part of the engine is starving oil and setting the warning.

Hi

The usual problems that would give you a delay in the oil warning light going out are...

1. Oil contaminated by fuel, and thin due to fuel injection system problems, and fuel draining into sump.

( How long ago did you last change the oil and filter ? Usually about....1 Yr or 12.OOO Mls)
Wipe oil from engine dip stick on tissue, and smell it for fuel !

Have you noticed you use a lot of fuel lately, and the car blows black smoke from exhaust on hard acceleration ?

2. Oil Warning light transmitter faulty. ( The Most Common !)
3. Oil pump pick up strainer clogged.
4. Oil pump faulty.
5 Oil draining back into the sump from the oil filter.( Faulty check valve )

If I were you, I would change the Oil and Filter, and renew the Oil Warning Light Transmitter, and go from there.
If you have a Master Oil Pressure Guage, fit it to the block when the O/W/ Transmitter is off, and run engine to confirm pressure is there from start up, and what it reads when hot, this will put your mind at ease.

Good Luck !

John.
