Provided that the oil level is sufficent the light means that somehow the engine computer is under the impression that there is no oil pressure. This may mean that there is acutally no oil pressure (bad- dont run engine) or there is a fault in the sensor, connector or wire (more likely). If the engine sounds normal when running ( no knocking or unusually noisy) u probably have oil pressure. Find the oil pressure sensor on the engine block toward the bottom of the engine and check the connection and wire, chances are you may just find the problem. beyond that you'd be getting major diagnostics.

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

Check oil light stays on


Your vehicle may have an "oil level" sensor built into the oil pan. If so, and the sensor is bad, the dash will constantly tell you that the engine needs more oil even if it does not. Checking the oil with the dipstick, a minute after the engine has been turned off on level ground is always the best way to check your oil. Try scanning the vehicles computer systems to see if there are any fault codes. The warning light may also be on a timer that just needs to be reset. The "Check Oil" light should be separate from the engine oil pressure warning light. As long as the engine oil pressure light stays off, you should be ok. Checking the oil pressure with a manual gauge would be a good idea as well.

Engine light comes and off periodically


Hi Have your machanic use a code reader to check why light is on.
If oil light stays on I would be worried about the engine not getting enough oil. Meaning the oil pump could be at fault. But there are other things on that light too. Good luck.

1988 toyota 4x4 pickup check oil light is staying on. checked oil level and was full.why does the light stay on


It means your oil pressure is too low to safely run engine. Causes might be a worn oil pump, a failed oil pump gasket, clogged oil passages from sludge, or badly worn crankshaft bearings.
If your toyota is not burning oil, or very little, I would take a look at the oil pump on your engine. After removal, they can be checked (and repaired) with a feeler gauge for proper working condition, but most people just replace with new.
If you want to be certain about the pressure reading, you can check pressure with a mechanic's oil pressure gauge. You have to run the engine just long enough to get a good reading on the pressure gauge, a moment or two.

I have a 95 grand am se 2.3 liter the other day my low coolant light came om i pulled over emediatley it was low i filled it and have been checking every time i go anywhere it is full and my low coolant...


You may have to reset it by putting in a code. You can find the code in your owners manual. In our Grand Am we have to reset the Check Oil light after we change the oil. For the oil light it is something like press the gas peddle in 5 times within 30 seconds....something like that. Good luck

Oil light on when oil is full


a loose connection WILL NOT cause flickering oil light unless your your oil is empty at the same time a connector is loose. This flickering is most likely caused by clogged oil ports or failing oil pump. When this happens there is insufficient oil running through the engine, causing the sensor to activate the light intermittedly. Have this checked immediately to prevent extensive engine damage. Hopefully this helps!!

Red oil light stays on 1/10 of mile after starting engine


Did you check the oil level?? Which i am guessing you did, it everything is running good and no change in engine performance or bad noise's coming from the engine. Then it's going to be your oil pressure sending unit, the oil pressure sending unit is inexpensive and you can pick it up at Auto Zone far less then the dealer and Auto zone will have the step by step instruction to replace the oil sensor. It's going to take just under an hour or less depends on how long you want to let the engine cool down before you work on it. Good luck and hope this helps. keep me posted, be glad to help.
