It could also be caused by not using the proper viscosity of oil.
I.E. it calls for 5W-30 and because it has hi-mileage and a mechanic or possibly even yourself decides to try 10-W30 or even 40 it makes the pump work harder especially in the cold weather, 9x's out of 10 if that is not the case it is the oil pump, I have rarely seen it where it was sludge causing the problem UNLESS the oil had never been changed in thousands of miles and then you'll find metal shavings!

Had the same problem with 1999 Grand Caravan. Changed out the oil pressure sensor. Had to add a little oil and problem solved. If problem continues, check for sludge in oil pan/clean oil pan screen. Last resort may be oil pump.

On the Mercedes C-240 the oil sencor light came on with the A service oil change .I had the oil changed and now the oil level light comes on. And this is on a 2005 C-240 4-matic .


Could be the person who changed it never ran the motor and then topped it off once the filter was full. Have you checked the oil level after you let the car sit overnight to make sure the oil level is on full? I would say it could be a bad oil level sensor, except that the coincidence of coinciding with an oil change is too obvious.

Oil light comes idling


You are low on oil, or your oil is too old. Check oil in the motor when the car has been sitting for at least two hours. The light usually doesn't flash until you are more than 2 quarts low. Change your oil.

Why does my oil light come on sitting at a red light or stop sign. But when I start driving it turns off?


Oil pressure is always lower at idle speed.I'm guessing you have high mileage.If your oil light is not coming on in drive at idle with the engine cold,but it does when hot,your bearing clearances are probably getting a little loose.Try using one quart of Lucas oil additive in place of a quart of oil at your next change(or just change it now).This stuff is thick and stringy,it helps the oil cling to surfaces.(if there is no change after this,you could try a new oil pressure switch-it's cheap enough.I actually had the switch on my 95 dakota leaking a LOT of oil at high pressure/RPM,which affected the reading).

Where do i find the oil pressure switch on the toyota tarago is there one or to I replaced the one on the side of the motor near the starter motor but the red oil light is still coming on


First, do not keep driving if the oil warning light is on or your oil pressure gauge has dropped. Stop the engine, let it sit for a few minutes, then check the oil level.
If the dipstick shows a full oil level, then low oil obviously isn't your problem. The oil pressure may be low because of a worn or broken oil pump, a plugged oil pickup screen in the engine's crankcase, possibly a plugged oil filter or excessive bearing wear. Or, the oil pressure may be fine but the oil pressure sending unit has failed. Further diagnosis will be required to determine what's wrong.
Perform electrical tests on oil pressure switch http://www.clarks-garage.com/shop-manual/elect-19.htm
Replace pressure switch as the cheapest means of repair to see if the lights go out .
The pressure switch will be located on the engine block.

Red oil light comes on intermittantly as does the


Assuming these readings are false, I have asimilar problem in my 540 which tells me allt the exterior bulbs are not working. The bulb sensor is faulty so I think you are safe in your assumption although the oil light showing would scare me, false or not. I suggest you get a service agent to cast his/her eyes over that one.

okay I dont think that one has anything to do with the other. I had this same prblem with my truck. The oil always had to be just past the full markor I got the oil light coming on. as far as the other prob youll need to start with fuel delevery and fire. check you timing, airfilter, spark plugs, pug wires basic troble shooting. then work your way up to the tpi, mass airflow sensors...ect if they apply good luck MrRodneyLong@Gmail.com
