Where is the air charge temp sensor located on a 2003 Ford Ranger with 4.0 liter engine?

On a 2003 Ford Ranger with a 4.0L engine, the Intake Air Temperature (IAT) sensor is typically located within the air intake system, before the throttle body. It's often integrated into the air intake duct or mounted on a nearby bracket.

However, precise location varies slightly depending on the specific trim and air intake configuration. You might find it:

* In the air intake tube: This is the most common location. Look for a small sensor with a wire harness plugged into it, somewhere along the tube leading from the air filter box to the throttle body.

* On a bracket near the air intake: Sometimes it's mounted to a bracket near the air intake tube, but still before the throttle body.

To be certain, I highly recommend:

1. Consulting a repair manual: A Haynes or Chilton manual specific to your year and engine will have diagrams and precise locations.

2. Using a Ford service diagram: Your local Ford dealership might be willing to provide a diagram, or you can potentially find one online (though ensure the source is reliable).

3. Searching online forums: Ranger forums (like Ford Ranger forums) will likely have threads with pictures showing the sensor location on similar vehicles.

Be cautious when inspecting the area; avoid touching any hot surfaces, especially if the engine is running or recently warmed up.
