P0521, oils pressure sensor or switch

[slepar]

Hey guys our family Calais is throwing the code p0521, from what I can research it's the sensor under the oil filter (v6)
My question is, it that called the oil pressure sensor or the oil pressure switch? I'm looking on eBay and I can find 2, the switch under the oil filter looks like the oil pressure switch on eBay but I just want to make sure I'm fixing the right one.

Any help from anyone who has changed one is much appreciated

Cheers

The oil pressure switch is located under the oil filter - fairly common problem in V6 commodores and is quite dimple to change

Yup ps easy to change.
The good ppl at Repco helped me out with sender and socket to fit (24mm)
all for under $100
Mine is a 3 pin connector.

3 pin is oil pressure sensor, 2 pin is just low light switch

Thanks for the help, which one would be causing the error code p0521? The switch or sensor?

Hey did you replace the sensor and solve the problem?
I've just had the same code appear on my car too. I'd love to know if there is any way to make sure the actual sensor is faulty and not a blocked oil pickup etc?
My car is driving normally but it's a worry.
Yes, I know if I replace the sensor and the fault reappears there's an oil problem but don't have a new sensor yet...

Hi, yes I replaced the switch located under the oil filter and it fixed the problem

I had this issue previously and it turned out to be a faulty oil pump with a fault flap/valve that was not closing correctly. https://clcarsblog.com/holden/ve/engine/oil-pressure-error-p0521/
