Dorman 645-514 sensor for the 2000-2005 Chevrolet Impala V6 3.4L and other vehicles is an ignition knock (detonation) sensor harness that connects the sensor to the vehicle wiring. It replaces an original harness that is missing, failed or corroded, and is designed to match the original in fit, function and appearance.
A corroded or damaged knock sensor pigtail can show up as a check engine light or an unsteady knock sensor signal, and a cracked or corroded connector may be visible on inspection with the engine off and cool. These signs alone do not prove the harness is at fault, since a faulty knock sensor is another common cause.
The 2000-2005 Chevrolet Impala V6 3.4L and the 1997-2003 Chevrolet Malibu V6 3.1L take this harness, one per vehicle, along with other vehicles. It is also a Monte Carlo sensor for the 1995-1999 Chevrolet Monte Carlo V6 3.1L and the 2000-2005 Monte Carlo V6 3.4L.
