2005 Parking Sensor issue
My passenger rear sensor appears to be having some trouble. When in reverse or drive it beeps like something is near it, it does this a few times until I reach speed or it times out. I don't believe it is realted to the button issue in a related thread. I'm wondering if I have a bad sensor or wire, and if so how to replace/troubleshoot it. I have cleaned the outside of the sensor, but no luck. Does the inside need to be cleaned? Can the sensor be replaced (for a reasonable price)?
