Parking Assist Malfunction

Got the Parking Assist Malfunction warning for all 6 sensors on my 2018 Tundra. I checked out two of the back one's and found one with Green corrosion. I replaced it and everything was fine for 2-3 days. Now it is acting up again, is it possible after the car wash i had it has damaged them with water getting in the sensors? or should i just check all of them?

Maybe i need to zero the code? Thanks,

 

Were the connectors corroded? If you haven't done so I would clean them up if possible and use some type of dielectric grease to keep the moisture out.

Probably not related to your particular issue if they were working when you replaced them. Sometimes the sensor needs to be rotated 90 degrees in any direction (clockwise or counter clockwise) to get it to clear.

 

water can make them act funky. I had it happen once and when everything dried out it functioned as normal. But if you found corrosion on one, I would check the others and see if they need cleaning too.

 

Did you ever get this figured out? I have the exact same issue. Starts out as clean all 6 sensors and then goes to malfunction for all 6.

 

I have had that message after a good powerwash. All I did was blow em dry/clean from both sides with compressed air. Maybe give that a shot
