Keep the ABS and traction-control systems reading wheel speed accurately with the NTK ABS Wheel Speed Sensor AB1987, a direct-fit front wheel speed sensor for the listed applications. It installs on vehicles including the 2004-2007 Buick Rainier, 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy, 2003-2008 Isuzu Ascender, 2002-2004 Oldsmobile Bravada and 2005-2009 Saab 9-7X — see the Buyer's Guide tab for the full list of 12 applications.
A failed front wheel speed sensor can illuminate the ABS or traction-control light and set stored wheel-speed fault codes. If a faulty sensor is the cause of those symptoms, replacing it with AB1987 restores the wheel-speed input the module needs; diagnose the fault before replacing to confirm the sensor is at fault.
