CBMS light came on in snowstorm- on 2006 Acura RL

Light came on I cleared the slush off the sensor, but has stayed on for several days although it has been dry and above freezing. ACC light then comes on intermittently.

If you you are referring to the ambient temp sensor, it could have been damaged by the snow. They are pretty delicate.
