LS430forme Posted February 18, 2008 Share Posted February 18, 2008 I just bought used 2004 LS430 couple months ago. But I recently found out that the rear parking sensor not working any more. Does anyone know this problem? Appreciate all the help. Quote Link to comment Share on other sites More sharing options...
Robert Young Posted February 19, 2008 Share Posted February 19, 2008 Is it just one rear sensor or all of the rear sensors?? The answer to that question would really help gining you quality advise. Quote Link to comment Share on other sites More sharing options...
LS430forme Posted February 20, 2008 Author Share Posted February 20, 2008 Thanks for replying to this post. The answer is all the rear sensors. No matter how close I stand next to the rear bumper while my wife is putting the gear in reverse. Quote Link to comment Share on other sites More sharing options...
Robert Young Posted February 26, 2008 Share Posted February 26, 2008 Sorry for the delay, I was traveling and then came back with a cold (just love O'Hare in the winter!). I'll assume the front sensors are working, since that means that all the parts common to both front and rear are OK. See the attached, it looks like you might have a problem with the common ground as about the only thing that would take out all the rear sensors simultaneously. I'd try grounding the individual sensors directly to the chassis and see if that brings them back into operation.Lexus_Wiring_Diagram_372.pdf Quote Link to comment Share on other sites More sharing options...
girrawarra Posted November 24, 2022 Share Posted November 24, 2022 This is an add on question. Have one missing rear sensor (RH) and looking to buy from Rock Auto. Question is when fitted will the sensor system accept and function OK with a non genuine? The Rock Auto (V70720226) one is German made and designated as outer sensor.
