The oil warning light comes on intermitantly while driving, sometimes, out of the blue. The oil level is fine and it comes and goes, I have changed the sending unit and that is not the problem.

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.

Your engine is worn, likely from insufficient oil changes. This causes the oil pressure to drop at low RPM's and causes the warning light to come on.

Change the oil pressure sensor.

replace oil level sensor

Verify that the engine has the proper amount of oil. The inertia from accelerating may be moving the oil in the oil pan away from the sensor and causing it to send a signal, then when you slow the oil levels out and the sensor go's off. I've had this happen alot with a taurus that I owned. The simple solution was to top off the oil to the correct level and the sensor did not come on again (until it ran low again, had a leaky oil plug on oil pan).

replace the oil pressure switch they do go wrong good luck.

Check the oil sending unit to see if it is giving a false signal.
However, I would trust it and maybe change the oil and filter if it hasn't been done within the last 3,000 mi.

Sometimes filters get plugged up or wrong oil was used which can cause this indicator to go off.

Good luck on this repair.

Hello. All of the warning lights are activated by a sensor. In this case since the engine oil level checks out fine the cause of the engine oil warning light is a bad sensor. You should be under full warranty. Have the dealership change the sensor. Joe

Check the oil sending unit for leaks.

Check the valve cover gasket for leaks that trigged down to the oil sending unit.

===

Oil sending send intermittent ZERO or low PSI data to the computer ECU.

It will triggle OBDII error code.

When you get a solid light the pull the code on reply.

Check for oil leak around the engine.

I have a 2000 Tacoma Extra Cab Pre Runner. When I put on my camper shell my check engine light comes on. Oil levels and tires are fine. I took my shell off and light goes off. I hauled alot of wood and the light did not come on. Why would the camper shell be trip-en my light? Ofcourse I am gunna get the code checked next week.
