MarkATH10W Posted May 31, 2023 Share Posted May 31, 2023 Hi all. I am trying to determine if my parking sensors require replacement: 1) front corner sensors seem to not beep until im very close to an object, and japanese lady starts talking... not really useful for helping me judge distances 2) rear corner parking sensors have never come on 3) rear center parking sensor have never come on 4) no errors indicated in the visual display upon turning the vehicle on... Is this a settings issues? or is this because they are fried? Quote Link to comment Share on other sites More sharing options...

John Harrison Posted June 1, 2023 Share Posted June 1, 2023 Hi. When I first got my 2008 Vellfire, some of my sensors were a little iffy. Just as a trial I sprayed each sensor with WD40 and now the all work!!! Don't know how it worked, possibly just cleaned out road dirt, but happy with the result. Good luck! John Harrison.

PaulE Posted June 1, 2023 Share Posted June 1, 2023 My front sensors only seem come on within a few inches of an object and the Japanese lady tells me that "Daddy made it" (sounds like) -have not really checked the rear ones but will try the wd40 Quote Link to comment Share on other sites More sharing options...

They could possible do with a clean, the rear centre only works when you are reversing, another thing to look for is the connectors behind the bumper Quote Link to comment Share on other sites More sharing options...
MarkATH10W Posted June 2, 2023 Author Share Posted June 2, 2023 All. Thanks for your responses. To clean/replace Do the sensors pop out from the front? If not, can i reach from behind without taking plastic bumper cover off? or does it require disassembly? Cheers, Mark Quote Link to comment Share on other sites More sharing options...
Geralt Posted June 9, 2023 Share Posted June 9, 2023 Just for reference, the manual says the sonar system should start working under 50cm. At 25cm the lights and buzzer should be continuously on. 1 Quote Link to comment Share on other sites More sharing options...
