EGR sensor?

Hello,

The EGR valve is located on the back of the engine.
A defective EGR valve can have restricted airflow and cause problem with the operations of the EGR system. Which can lead to loss of power and decreased fuel economy. The EGR valve and fail stuck open or stuck closed.

Here is a helpful video:

I have attached the diagnostics process for the EGR and replacement diagrams for your reference.

Please let me know of any questions.

Thank you.
