Change an oil sending unit?

Hello there Danny and thank you so much for the help. I shall check that out. Because this is one error that is drives me crazy when it happens. Also, on the way home I had just bought a MAF to replace the one I have on there and the light went off by itself on the way home. Does this mean the problem corrected itself? My van has been sitting since this Covid stuff started happening. Normally I drive my van at least 3 to 4 times a week. Here lately it has been sitting. Do you guys thing having the van sitting for a while has cause this error to appear again before going off etc?

I'm sorry I posted my last question to the wrong spot. I meant to post it here. I took my van in to get a new oil pressure switch installed and now I have a error code of 1101 manufacturer's code that I didn't have before I had them to put the new oil pressure switch in. Any ideas what the problem could be? I had no error codes before they touched it. Would changing oil pressure switch cause this error code?

Where did everyone go? Anyway I hope everyone is staying safe out there. :-) Oh by the way my oil pressure for my van is normal between 40 - 60 psi I can't remember actually what it was but I know it wasn't below 40 psi etc. I want to say it was 45 psi and praise the Lord it hasn't dropped to zero.

Hello there. Lol. Glad someone is still here. I just wanted to let Ken and the rest of the crew what my oil pressure was in my van and I had finally gotten my oil pressure switch fixed. The oil pressure level goes where it normally goes even when it gets cold. Etc Before it wasn't working correctly. It cost me $140.00 to get it fixed too. Labor was $90.00 and the cost of the part was $44.05. But thank you for taking the time to write me back. But I am sure the others are just busy etc. Do you think I was charged to much for the repair job? I did shop around and some where higher then the price I paid there. And the ones I did find cheaper was only like 2 or 3 dollars cheaper etc. Next repair is brakes.
