This is just a thought , but i would first replace oil pressure switch as this is cheap start to solving your problem , i wonder if you have caused air leak when chnageing oil sensor in sump by not sealing sump correctly ,? the other thing may be you oil pump is worn causing incorrect oil pressure , which may be reason for your oil problems in the beginning , hope this helps , i know what its like when you run out of idea's good luck .

Done oil change & oil filter done oil sensor & red light coming on after 20 mins. Can u help?


Since there are various different warning lights exactly which warning light is appearing after 20 minutes?

If it is the oil service warning light that is appearing then that has to be reset manually when the oil service is done.

WHAT IS THE MEANING OF THE YELLOW SYMBOL OIL PRESSURE WITH AN EXCLAMATION MARK


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). .

Lost oil pressure in a 1999 540i and timing chain noise


from the book the oil pump is driven by a chain from the crankshaft. It is very possible that the oil pump has come loose and thrown/broken the pump chain. It will require a sump removal to check it out. recheck the oil level as what you read may have been a froth level . there is no reason for extra oil unless it was overfilled to start with or there is water contamination ( white /grey oil)

How do i reset the oil change light? 99 grand am se 6cyl


That light should reset itself after you changed the oil .If you have changed the oil and it doesn't reset ,try disconnecting the batter for about 5 mins. check your milage, see how many miles you normally drive before that light normally comes on. That is so, if that light dosen't come on ,you will know its time to change the oil. If that light doesn't come on at the right amount of miles,have your oil changed at the dealer and ask them to check the oil change warning light .If they find nothing wrong ,no charge . This warning light is fairly new ,in the old days people just guessed ,its about time to change the oil !

1990 regal starts, runs for 2 to 3 min then dies, changed fuel filter, crank sensor, coil packs, it has 45 pounds of prs. to rail. im stumped


hi, please check you oil level, ( on level ground). when the car is running place an old rag in front of you and take off the oil filler cap (be careful not to get near the fan, fan belt) if no oil comes out of the filler hole possible fault: oil pick-up pipe (in sump partial block), / oil filter in sump ( blocked), oil pump worn, oil relief valve (returning oil back into the sump), spring weak / broken. the (E C U) ENGINE CONTROL UNIT has many sensors that can stop the engine: but try cleaning the (EGR) ENGINE GAS RECIRCLING VALVE, this valve recycles gas back in to the engine, ( must be CLEANED with BRAKE FLUID) this is a VERY DIRTY job, as this gets block with carbon (EXHAUST PARTICULES). the E C U will detect all of these sensors: the (ECT), TOP OF ENGINE engine coolant temperature sensor rough tick over, (HO2), EXHAUST DOWN PIPE, heated oxygen sensor checks mixture of fuel, can adjust air / fuel, it tries to keep car going / may flood engine. (M A F) mass air flow, adjusts fuel / air retio this sensor can so much fuel to the engine it may flood it. flooded engine mean WET spark plugs. i would put it on dianostic machine to check these out before paying for extra sensors. gerry

The oil pressure light and alarm keeps going off on my 2000 vw polo. it is only when the engin is warm after approx 10 miles. sump and strainer have been cleaned and also new sensor been fitted and oil...


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.

Need to change the oil pressure sqitch on a vw passat


Hi before you do an oil change try seafoam in the engine oil. this can sometimes fix the problems you are having, I used seafoam in engine oil and fuel and breather line and ran engine for 100 miles, but don't run hard, and its cleaned all the sump and oil veins in the engine, as checked with a scope looking though the oil sump plug. it did a really good job, my engine is a bit older than yours 1994. oil sensor is at the bottom of the engine on the sump. pressure sensor is above the oil filter it has a single wire conection

High oil Consumption, BMW M5


Look for Castrol TWS 10W60 Motor Oil. This car should not burn so much oil, you need to use a different kind. It is recommended by BMW as well. I also heard the VANOS isnt an issue anymore, can be fixed with a different MAFF. Good luck!
