What Is a Steering Position Sensor and Why Is It Important?

In your steering column under the dash, you’ll find a donut-shaped sensor. That’s the steering position sensor. Its job is to monitor the steering angle at all times and report the data to the ECU, which in turn controls the power steering system. The sensor exists to adjust power steering boost at low and high speeds. Read more here about how a steering position sensor works.

How to Diagnose a Failing Steering Position Sensor

A failing steering position sensor is a pretty big deal because it causes erratic steering, which can be quite dangerous. If you’re experiencing fluctuating steering boost and if your traction control light is on, then you might have a failing steering position sensor. The good news that it’s really easy to diagnose a failing steering sensor. You just need an ohmmeter, five minutes, and this handy tutorial.

How to Replace Your GM's Steering Position Sensor

There are two different ways to deal with a failing steering position sensor

  • Replace it.
  • Bypass the EVO solenoid valve, which makes the sensor unnecessary.

Replacing the sensor is a simple process that takes less than an hour. You can find the steps on how to replace your steering position sensor here.

Bypassing the EVO with GM’s actuator kit (part no. 19168825) is a more permanent solution. The steering position sensor along with the EVO solenoid valve found in certain GM steering systems are prone to failure.
