Where it lives

For C0048, the part to look at first is the sensor named here.

Check these first

2. Test the brake booster travel sensor wiring for opens and shorts
3. Check the brake pedal and booster for mechanical faults
4. Calibrate the brake booster travel sensor per service data
5. Replace the brake booster travel sensor if it tests bad
