Could anyone tell me where it is loaceted. 2001 v70 2.4t.

BTW. THe car is for sale. 55K miles.

The oil pressure sensor is located on the front of the engine about in the middle of the engine it has 1 wire going to it.Is there a special reason you are asking? Is the oil light on?If it is it is most likely not the sensor that is bad the car has low oil pressure.There are o-rings that go bad between the oil pan and the engine.They will need to be replaced.

Yes... The low oil preasure is on. I was thinking it's the sensor so I bought one. Do I have to remove the oil pan? What O ring is it? Any picture?

Thank you so much for the help. :D

To replace the o-rings yes you have to remove the oil pan.I will work on trying to get you some pictures.You will have to replace about 4 to 5 o-rings.You will also need some special gasket sealer that you will need to buy from Volvo.
