Park Sonar System

Is anyone familiar with the Park Sonar message???
“Check Park Sonar System”
How can this be corrected???

 

Is there damage to the bumper? They misalign and/or break fairly easily.
If not, start w cleaning them, and checking connections.

BTW welcome!
When you find the fix, post it, it’ll help others.

 

Chew - Thanks for response. Will investigate your suggestions and will reply.

 

Did you ever figure out the issue I’m having the same problem on my 21 trd pro I heard that if you replace the factory sensors on a 21 and up with non oem ones it won’t work I’m thinking that might be my issue but not sure I tried cleaning the with wd40 but haven’t taken them out to see if they’re oem or not but it’s all of them on the rear not just one

 

Purchased a new sensor (only buy a Genuine Toyota Sensor). The sensor will be installed within a couple weeks. I will make another posting shortly. This should correct the issue.
