What would be the casualty of a failed brake pedal sensor?
It is showing up in ECM trouble codes.
It is a daily driver in rough winter.
Should I replace it with Volvo part number 9441116 for $92?
The cruise control will cease to work as that part’s major role is to assure cruise will still go off with brake if the brake light switch fails.
Pump brakes until pedal is hard to dump booster vacuum or the or ring on sensor will get sucked inside booster as you pull it out.
