When engine warms up the oil light comes on and stays on. Have had the oil changed, there is no noise or vibrations from the engine...it runs smooth. Could it be a sensor or oil pump problem? (engine light is also always on because of a connection problem with the wiring...have had it fixed twice but it comes back on after a month or two...related maybe?)

The oil pressure warning light comes on when the oil pressure drops below a certain point. This varies from vehicle to vehicle, but is usually somewhere below 10psi which is a dangerously low pressure. If there is a wring problem this can also cause the light to come on, but this is usually intermittent or just on all the time. What needs to be done is to connect a good pressure gauge to the engine and see what the oil pressure is. If it is actually low this can be caused by a problem with the oil pump, or possibly excessive wear in the engine. If the oil pressure is OK, then diagnosis needs to be done to find why the oil light is coming on when it shouldn't.

Thank you for the quick reply. I had the oil changed at Midas and they didn't note any leakage and I don't know if they would check the oil pressure so will mention that to my sil. I do know there are some wiring issues and that the catalytic converter is ok. I have a code PO1698 which says there is no communication between PCM and TCM. Could this be also effecting the oil light as well as the engine light?

our oil light came on.. changed oil and filters and still comes on and engine sounds like its missing is it...
the hotter it gets the more it smokes. It is full of oil and water. one says it's the motor others say its a small leak. the motor runs fine and show no lights.
After driving for some time and the fuel tank drops below below half tank, the engine shuts off but start right ups. The only light that comes on is the check oil.
If i coast the turn, no clacking. If i'm turning and not move the steering it still clicks uniformly. No noise when driving straight and turning slightly.Louder when U turning.Suspension is tight.S...
