Front Parking Sensor Blocked ERROR

[Rjpear]

I am getting a Front Parking Sensor Blocked Error specifically following a Car Wash (Drive through) in Freezing Temps. I assumed this was just ice build up on the Bumper Sensors but after manually inspecting I see nothing. Is there a lower (Under bumper) sensor that I am not seeing? Thanks

This happens often, in heavy rain, on my truck.

FYI - there was / is a CSP for some or all Lightnings to help with this... it is essentially a set of software updates and related software actions.

On my truck, the dealership (a good dealership BTW) checked this out and then recalibrated the front sensors. When in heavy rain, this recalibration reduced the duration of the front sensors yelling at me (OMG OMG FAILURE! FAILURE! WARNING WILL ROBINSON! etc...) from 20+ seconds per event, to about 1 or 2 seconds per event. That has helped a lot for livability and my peace of mind while driving

Good Luck!
