did you check the brake master cylinder fluid level? You may have a leak.
this is the P0719 code which is sensing a problem with the brake switch, could be a bad switch or wire harness

This is likely a faulty master cylinder. As aforementioned, look for leaks and identify if the brake fluid level is low. The master cylinder will cost around $50-80, depending on where you buy it. GL!
