The oil light comes on after start up?

Did they change the oil filter as well? There is an oil pump regulating valve that sounds like it is stuck open. Here is the location you might be able to clean it out and have it work again but if not, I would get a new valve. When they dropped the pan did they clean the oil pump pick up? Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.

in cold and mild weather the oil light comes on and it beeps 3 times. On very hot days it does not come on or beep at all. Had recommended parts changed and oil changes, but same issue

Hmm, there is a slight chance the oil pressure sensor is bad, can I ask if the engine makes a rattling sound at idle, can you upload a short video of the engine idling so can hear it? The location of the oil pressure switch is on the oil filter housing which you say got replaced, did they use the old switch? If so this can be the problem, also, I have ween the instrument cluster give these kinds of problems, you might want to do a CAN scan to see if a code is stored for it.

This video will show you how:

Please let us know what happens.

Thank you Ken. I'll have access to the car this week. The engine does not rattle. I'll send a video and check the pressure switch and codes. Thanks

Sounds good have a great week!

Hi Ken, here are 2 videos, engine running and the oil light blinking/sound.

Thanks for the video, at this point you should remove the oil pressure sender and install a manual gauge which you can rent from the auto part store. Insert the gauge and start the engine, this will tell us for sure if the engine is having an issue or the PCM. Thanks for the videos, they helped.

Thank you Ken

You are welcome, have a good weekend!
