Question

I have a 2000 Ford F350 6.8L with engine code P1151, how can I fix it?

Answer 1

HI there

This code is for lack of O2 sensor switch lean on bank 2.

This code is the result of either to much air or to little fuel on bank 2. Best place to start is by checking for vacuum leaks on bank 2. Most common issue would be a leaking intake manifold gasket.

Answer 2

P1151 FORD - Lack of Upstream Heated Oxygen Sensor Switch Sensor Indicates Lean Bank 2
