OEM Part Number: 25070-CD00A
Price: $75.00-$80.00

So I finally buckled down and added info in here for how to change your oil sending unit also known as an oil pressure sensor. Hoping this helps some of you guys out. The beginning of my problems was when I noted 0 psi on my oil pressure gauge (stock on SE-R) after running diagnostics and checking to wire I discovered that the sensor was bad.

The sensor can range in price for you VQ guys depending upon a SE-R or just SE. The difference between the two is 2 (SE) and 3 prongs (SE-R) for the oil pressure gauge.

• SE $20.81: https://www.courtesyparts.com/oem-parts/nissan-oil-pressure-switch-see-description-below-252404m40e

Given that I drive an SE-R I had to pony up the extra cash for the $80+ unit

Ok onto the install. There’s a lot of bad info out there telling you that the only way to remove it is going through the passenger wheel well after removing the wheel. I originally did this then found out I wasted my time. We have a grease pit in our garage. If you guys are lucky enough to have a lift or pit in your garage this will make installation a breeze. If not pull out your jack stands or ramps and set your car up for an oil change. By draining your oil you can avoid a mess when you unthread the sensor.

You will need:

• Oil changing materials socket, drain pan, filter, new oil
• Deep 24mm socket to accommodate the sensor to fit inside when threading
• 1/2 in drive small breaker bar( I found a ratchet too big and didn’t give enough space to fit, I tried extensions and articulated drives as well without success. They just didn’t work)

Onto the pics:

Location of sensor is above oil pan and drain plug to the right side ( sensor is still plugged in and wire loom can be seen.

After unplugging sensor and using socket to remove I used Teflon pipe tape on the new sending unit threaded it in by hand and used the socket the rest of the way. Be careful not to overtighten and set the sensor so that the harness and plug can be easily removed if needed later.

That’s it! A pretty easy fix to something that would cost over $140 to have done at the dealer. Once the car was on the pit and I had my tools the job was done in under 25 mins.
