CM871: Is it safe to run truck without a crankcase pressure sensor?

[RMezaJr]

While OTR I got a fault code saying the crankcase pressure voltage is less than normal. Upon inspection, I found a frayed wire in the harness near the Crankcase Pressure Sensor. I called Cummins and was told I would have to buy a complete harness. The damage is too close to the connector, I can’t splice it back together without removing the pin. Would it be safe to run the truck without that sensor until I get home and can repair it?
