In this video, we're going to show you how to replace the fuel injection pressure sensor. This is a 2006 Ford Explorer with a 4.6-liter motor. Pretty much the same for any Fords from this era with this engine in it.

If you need the part in this video, click the link down in the description to We want to be your source for all your parts needs.

Here are the items that you'll need for this repair.

With the hood open, you'll want to locate the fuse box on the driver's side right behind the battery. Pull up on this tab. When you have the engine running, you want to pull out this number four 30 amp fuse. I'm going to pull out once beforehand just to make sure it'll come out. That is the fuel pump fuse. You'll have the engine running, pull that out, and then the engine will die. That will relieve some of the pressure in the fuel line. With the engine running, pull out this fourth 30 amp fuse.

Loosen and disconnect your negative battery cable. It should be an 8 millimeter. This looks like about a 13 millimeter.

Your fuel injection pressure sensor's right here. There's two leads: electric and vacuum. Vacuum, twist, and pull. The electric tab right on top, push down and disconnect, and two 8 millimeter bolts hold it in place. Remove the bolts and twist on the sensor and pull up and out. This side is our old sensor from our 2006 Ford Explorer.

Here’s a new sensor from 1A Auto. Cosmetically, they have some slight differences, but everything's going to bolt in, fit, and function just like the original. The plugs are the same. The vacu-port is the same. I'm going to carefully clean the surface with some carburetor choke and throttle body cleaner. Spray it on the rag. Then basically wipe out from the middle. Make sure we don't get anything inside.

This cap from my motor oil, just take a little bit of residue from the motor oil. You don't want to put too much on here, just really, really, light coat of oil to make sure it goes together correctly. Then, push it down and in. Put your two bolts back in. By hand at first to make sure they go in correctly, and then tighten them up with your 8 millimeter socket ratchet and extension. Tighten them up evenly. Get one side seated down and seat down the other side. Once you get them seated down, tighten them about another 1/4 turn.

Reconnect your vacuum line, and reconnect your electrical lead. Make sure you hear a click when you put this in. Put your fuel pump breaker back in, or fuse back in. Put this back on.

Reconnect your battery. Turn your key on once or twice, just to let the fuel pump build pressure, and then start it up.
