Keep your stability and traction control systems reading the wheel accurately with the Standard Ignition Steering Angle Sensor SWS40. It installs as a direct-fit replacement for the 2010-2014 Subaru Legacy, 2010-2014 Subaru Outback, 2012-2016 Subaru Impreza, 2013-2015 Subaru XV Crosstrek, 2014-2021 Subaru Forester, 2015-2020 Subaru WRX, 2015-2020 Subaru WRX STI and 2016-2021 Subaru Crosstrek.

  • Measures steering input: reports the steering wheel's angle and rate of rotation to the vehicle's electronic stability and traction control modules.
  • Direct-fit replacement: designed to replace the original sensor on the listed Subaru applications.
  • Restores system data: if a faulty steering angle sensor is the cause of a stability-control or traction-control warning, this part replaces it.

A failing steering angle sensor can set a stability/traction control warning light or cause the system to behave erratically. Because these symptoms can have other causes, diagnose the fault before replacing the sensor.
