CEL Code P2098

[superduty]

Have any of you guys seen this code before? Auto Zone wasn't able to tell me the problem related to the code and no dealerships open at this time of the day. The truck seems to be running ok and I need to make a 175 mile trip tomorrow to get back home.

I believe it's the O2 sensor measuring your fuel mixture as being to lean. Do you have a CAI or a tune? If so, I would try running the stock filter to see if the code returns. Could be a bad sensor or bad electrical connection at the sensor.

Everything is stock on the truck. Appreciate the help!

I filled up on gas the and the light extinguished. Guessing the fuel filler port door may have not properly closed.

Glad you figured it out. Also, thanks for letting us know what it was, in case someone else has this happen.
