Brake Pressure Sensor Circuit

[brc19761]

I have a 2011 Ram 1500 crew cab with the 5.7 hemi. I have a problem with the abs light coming on intermittently. The codes are c121d (which is the brake pressure sensor circuit) . Where is this part located? How do you replace it? I cannot find much about it online.

Thanks

In modern vehicles the brake pressure sensor is normally located within the ABS pump and cannot be replaced separately from the ABS pump.

Is the abs pump located near the master cylinder. The part that has all the brake lines running into it?
