Nakakabili ba ng sensor lang? Found out by isolation that one of my sensor is not working. Pag plug mo siya sa module straight beep, beep sound pag reverse mo even without obstruction. pag inalis ko yun defective na sensor gana na ulit siya although isang sensor nalang. I have it in my patrol since I can't remember when. It's been a valuable add on to any vehicle, IMO.
