Does anybody know the P code for reading the fuel pressure sensor?

What is your question?

Using OBD lite app with an ELM 327 Bluetooth reader. It shows No Data when I select the Fuel Pressure item. 2009 Chevy Traverse. I think the app has an option for putting in other codes by the number.

What makes this problem better or worse?

Stepping hard on the gas. Feels like it's misfiring.

How long has your 2009 Chevrolet Traverse had this problem?

1 week, just bought the car
