Q: The code reader for my engine light says P0306P. What does the second P mean?

The code reader for my engine light says P0306P. What does the second P mean?
My car has an automatic transmission.

The P means powertrain. The second P is not normal and may just be the scanner you are using. This vehicle does not use the second letter P. I would disregard it. As far as the P0306 it indicates a misfire in cylinder number 6.
