I had a diagnostic check to find the reason that the "check engine" light came on and the code p1150 & p1151 came up. What does that mean?

It means it's probably time to replace the sensor, before the converter, it is not switching, or changing from lean to rich. It could also be poor quality fuel. Sets usually during or just after hard acceleration?
