View guide: PCV Valve Change (3.8L engine)
Written by: mrdiy

---

The PCV valve is located under the pressure sensor.

To access it, you will need to remove the plastic engine cover first.

Spin the oil filler (the whole thing, not just the cap) counter clockwise to remove it.

The gray cover will now lift out of place.

Replace the oil filler to prevent dirt entering.

The pressure sensor is located near the serpentine belt, at the front of the engine.

Disconnect the wires to the pressure sensor.

Turn the pressure sensor counter clockwise to open it.

Be careful not to damage the clips on top of it.

If the pressure sensor does not easily open, you can remove the top half, where the wires connect, by releasing the clips on both sides and pulling straight up.

It should now be easier to open it.

There is a spot where you can turn the sensor with a wrench if you can't get it off by hand.

You will now see the PCV valve.

Just pull up on it to remove.

There is a rubber ring-type gasket on the PCV valve.

Remove it, and unless it is brittle or cracked, it can be reused on the new PCV valve.

Install the gasket on new PCV valve.

Push the PCV valve into place.

Reassemble the pressure sensor.

Reattach wires to pressure sensor.

Reinstall the plastic engine cover.
