Where is the DPFE sensor on a 1996 Ford Ranger 4.0L 6 cylinder engine?

The DPFE (Differential Pressure Feedback EGR) sensor on a 1996 Ford Ranger 4.0L 6-cylinder engine is located on the passenger side of the engine, near the back of the intake manifold. It's usually attached to a vacuum line and sometimes has a small electrical connector. It's a relatively small sensor, so you might need to look closely.

Because its exact location can vary slightly depending on specific model variations, a picture or diagram specific to your year and engine would be most helpful. You can find such diagrams online through sites like Ford's own parts website (using your VIN) or various automotive repair websites. Searching for "1996 Ford Ranger 4.0L DPFE sensor location" with images may also yield useful results.
