Good morning.

This code appears when there is an issue with the fly by wire system for the fuel pedal.

I would check the connector at the throttle body. It is a common failure for this issue.

Did anyone check for codes? There is a code stored in the system and that will help narrow the area of failure.

Hello MONKNICKLES,

If you decide you would like to conduct the scan yourself here is a link to an article from this site that features written step by step instructions and pictures explaining how to do the scan yourself. Also, I have included a link to our YouTube channel with a how to video on code scanning.

This is applicable even if your check engine light is not on.

Most scanners are inexpensive to purchase, you can purchase one online from sites like Amazon.com

Once you have the codes please get back to us with the code number(s) so that we can further assist you. We are always happy to help.

Thank you for visiting 2CarPros.com.

Kindest regards,
