The sensor can wear out, and road debris, accidents, water and road salt can damage it. A rear that sits at the wrong height or a suspension warning on the dash can mean the sensor is failing. The air struts, compressor or wiring may also be behind it, so with the engine off, look the connector and wiring over for damage or corrosion first, and leave electrical testing to a shop.
