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!

This seems to be a common issue. Our 23 has had the CSP done a few months ago but recently started going nuts on the left center sensor. It was at the dealer last week and went to pick it up Friday after 'everything is good, we replaced a module' only for my wife to call and say it was doing the same thing less than a mile from the dealer. Back it goes tomorrow, this time I told them they are giving us a vehicle to drive. Certainly seems like a calibration or software issue.
