What causes lean codes?
Lean codes can also be set if the engine is not getting enough fuel. The underlying cause might be a weak fuel pump, low voltage to the fuel pump (which prevents the fuel pump from spinning fast enough to deliver normal fuel flow), a restricted fuel filter, or possibly a leaky fuel pressure regulator.
