J1939 code SPN 1067. Below — how the fault is worded at the factory by Bendix ABS/ESP, Knorr-Bremse EBS, MAN, Meritor (ex-WABCO) and SITRAK, and what the second half of the code (FMI) means in the standard.

Safe to drive. Below — how much time you have and what happens if you keep going.
This is an electrical fault: an open, a short or a bad contact in the sensor circuit. The value it measures is most likely fine.
You can drive. But until the circuit is repaired this system runs blind and cannot warn you about a real failure.
