this sensor sits right in the region of the front bumper. because these cars sit low to the ground, that area is commonly scraped and compressed. this can damage the wiring and/or the sensor. if you're handy, you may be able to address the issue yourself. if not, or if you just don't want to, a decent mechanic should be able to take care of it. mine was able to simply repair the wiring and the sensor has been working fine since then.
