I believe you need a 26mm spanner or socket (would need to be a really deep one tho).

Unplugs, then simply unscrews.. and screws back in.

EDIT: .. or is 23mm?... cant remember exactly. Might wanna measure it first if your going to buy tools.

How would i change it is it easy

If you expect help, your first step should be to provide a full description of your car and engine and any other things that might be relevant. Do you have a v6 or a v8? If the latter it's a V8 is it a Holden engine (5.0l or 5.7l) or a Chev engine (5.7l). We like to help but we are not mind readers !!!

If its the same thing as the oil pressure sensor, I changed one of these without knowing anything about cars, having only ever changed a wheel before. My warning light was intermittently on, and was quoted $300+ from a range of places to sort it out.
For my 5.7L SS I got a 27mm socket from supercheap, you need something with a long shaft as it has to reach through a tight gap. Its down near the back of the engine on the passengers side, pretty hard to see if you're not sure what you're looking for. Unplug the clip in cables, then it's a game of operation to get it off and on. Got quoted $190 for the part from holden, $220 from supercheap, but got a $39 brand new legit GM (supposedly) one from a place in melb I found on ebay (picked it up in person to make sure). 7 months on no problems.

Sorry its a vt commy v6

The oil pressure sender on the V6 is located on the oil filter adapter. Looking at the diagram, if you remove the oil filter you can probably remove the sender with either a ring spanner or shifter as some of the previous posts have indicated. If you want to keep the oil filter in place you will probably need a deep socket. Not sure what size socket would be required for a V6. On the Gen III V8 you can only remove the sender with a long socket due to lack of clearance, and even then it's a struggle.

When You change it, Note the thread does not go all the way in ! If you attempt the screw it all the way in you will crack the Oil filter adapter housing, Just a FYI caution :)
