check engine light high voltage from oil pressure switch?

Post by jj55chevy » Mon Dec 24, 2018 9:57 pm

is anyone familiar with this condition? I just bought my 2012 Caprice PPV a week ago and the check engine light came one. I took it to O'riely's and they scanned it, came up as high voltage from the oil pressure sensor. Should I roll the dice and buy a $70 switch and hope that is the problem or are these cars known for some other ailment that would cause this? any help would be greatly appreciated!!

just an update: it was the oil pressure sending unit...$70 later and it's all good!

Good to know. 90% of the time, it's a fault with the sending unit.

I'm not sure what brand it was, I bought it at Orielys for about $74. it is located at the back of the engine on top just like the old small lock chevy oil pressure switches. it's actually not too hard to replace. they reset the code at orielys and I have had no problems since.

Well I changed out the sensor and it fixed the P0523 code problem... What a pain in the ass to change out this sensor and filter... It looks as though the sensor was seeping up through the electrical pins...

Does anybody have a part number-either GM or parts store-for the sensor and screen? I tried finding it on GMPartsDirect with no luck.

Thanks,
