GM Genuine Parts 13579089 Brake Pedal Position Sensor

This brake sensor switch was the solution to fix the check engine light problem. In my case the code for the check engine light specifically indicated that this sensor was the cause for the fault. This was a great savings over purchasing it from the dealership. The hardest part of the installation is getting to the part. The sensor is on the Top of the brake pedal under the dash. So a little twisting and contorting is necessary to install it. One bolt and one plug. Do it yourself at save $$$ over dealership labor. There are some great videos on YouTube to show you how to install it. Don forget to disconnect the battery when replacing the part. Not a hard thing to do but practice getting into the proper position to gain the proper access.
