P053E
Crankcase Pressure Too High
Moderate severity
What it means
The crankcase pressure sensor reports a value above the safe upper threshold. Excessive crankcase pressure pushes oil past seals and contaminates the PCV path with mist - causes are clogged PCV system, frozen breather hose, or excessive blow-by from worn rings.
