On the 1.9L diesel, there is one. It is located under the vehicle and is part of the exhaust system.
To get you started, here is a link that explains in general how one is replaced. You can use this as a guide.
If you look at the attachments below, they include the directions for replacement and pics specific to your vehicle.
I hope this helps. Let me know if you have other questions.
See pics below. Note: The directions below are for all components on the exhaust system. I'm adding them in the event they are needed.
