The oil pressure sender is used to illuminate the oil pressure light on the dashboard when there is no pressure in the lubrication system. You'll notice that the light goes on when the engine is not running. Once the engine is started, the light goes out. Over the years, the sender can fail, sometimes even leak from the sender housing.

Replacing the sender is relatively easy, although it does require removing a few things for access. There isn't a lot of room to work with here. It is easier to physically remove the sender from underneath the car, although the pictures in the article show the sender mainly from the top for purposes of clarity.

You'll need to drain the oil from the engine to replace the oil pressure sender. You'll also need to remove the air filter housing as well. See our articles on Engine Oil Change and Air Filter Housing Removal for more information.

The oil pressure sender is located just to the left of the oil filter housing (green arrow).
Figure 1

The oil pressure sender is located just to the left of the oil filter housing (green arrow). It's a bit difficult to gain access to. You'll need to move a few things around.

Loosen and remove the 8mm bolt (green arrow) holding the dipstick (yellow arrow) to the oil filter housing.

Loosen and remove the 8mm bolt (green arrow) holding the dipstick (yellow arrow) to the oil filter housing. Pull the dipstick up and out of the oil pan.

You now should have enough access from above to reach the sender.

You now should have enough access from above to reach the sender. Squeeze the two locking arms (green arrows) on the electrical connector and pull it off the sender.

Shown here is the sender from below the car, looking up (green arrow).
Figure 4

Shown here is the sender from below the car, looking up (green arrow). You may find it easier to loosen the sender from this position.

The last step is to loosen and remove the sender using a 24mm wrench.

The last step is to loosen and remove the sender using a 24mm wrench. Note that the oil filter housing has been removed in this photo for purposes of clarity. Simply screw the new sender in place and plug in the electrical connector.
