If unable to establish a root cause. Remove the PCV/Crankcase Pressure Sensor and hose assembly and inspect for presence of frozen moisture/condensation in the Crankcase Pressure sensor and hose assembly. If frozen moisture is present, replacement of the Crankcase Pressure Sensor will not be necessary. Please allow the Crankcase pressure sensor and hose assembly to thaw out and the moisture to drain completely. Use a combination of light compressed air and a shop towel to remove any residual condensation/moisture. Note: If the ambient air temperatures have not been below freezing but moisture is still present in the Crankcase pressure sensor. Remove the moisture using a combination of light compressed air and a shop towel. Once completed clear any remaining DTC's using GDS and evaluate.
