Question

How do I fix the code p0731 on the 2006 Ford Expedition 5.4L?

Answer 1

This code is for an incorrect gear ratio issue. This can be the result of low transmission fluid, however, this could also indicate a mechanical issue with the transmission. This needs to be diagnosed but check the transmission fluid to start with.
