Keep your anti-lock braking and traction-control system reading wheel rotation accurately with the Standard Ignition ABS Wheel Speed Sensor / TPMS Sensor (MPN ALS501). It installs as a direct-fit replacement for the listed applications, mounting in the rear-left position on the 2005-2007 Ford Five Hundred, 2005-2007 Ford Freestyle, and 2005-2007 Mercury Montego. This part is cataloged under both names — ABS Wheel Speed Sensor and Tire Pressure Monitoring System (TPMS) Sensor.
- Wheel-speed signal: monitors how fast the wheel is turning and reports that signal to the ABS and traction-control module.
- Dual-cataloged function: listed as both an ABS wheel speed sensor and a Tire Pressure Monitoring System (TPMS) sensor, so it may appear under either name.
- Rear-left position: designed to install in the rear-left location on the listed vehicles.
Signs the original sensor may need replacing include an illuminated ABS or traction-control warning light and stored wheel-speed trouble codes for the affected circuit. If a failed sensor is the cause, replacing it with ALS501 restores the correct signal to the module; diagnose the cause before replacing, since these symptoms can have other sources.
