Corolla Radar Sensor Malfunction

Radar sensor stopped working on my 2011 Toyota Corolla with a gasoline engine. Getting an error message and fault stored in the error memory, causing system failures and a constant warning light. Anyone experienced something similar? It has 157099 km on it. I've checked around the sensor, looks clean, but not sure what else to do.

I had similar issues with my old Opel Insignia. Safety systems were going haywire. Does the error message indicate anything specific, or is it just a generic 'sensor malfunction' type of warning?

Thanks! The error message isn't very specific, unfortunately. It just says "Radar sensor malfunction." Did you manage to fix it yourself, or did you have to take it somewhere?

I tried cleaning the sensor, but it didn't help. I had to take it to a workshop. They ran diagnostics and recalibrated the radar. That solved the issue.

Okay, thanks! Seems I should visit a workshop then. You were right: the sensor was simply dirty. Cleaning cost me 45€ - money well spent!
