This happened to my wifes car, 2002 AWD. I ended up changing the sensor and the check engine light disapeared. The sensor is located near the fire wall on the RH side. If you open the hood and stand on the RH side (passanger side) and just behind the valve cover is the sensor. It connects to a couple of tubes and there is a single electrical plug.

I was told that the 4.0L was notorius for the sensor going bad.

Hope this helps.

This sensor typically called the DPFE sensor (Differential Pressure Feedback - EGR).
