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.
xHeart » The new Volvo brake pedal sensor is here. The other side says ATE!
Where would the o-ring seats? Or what to expect when the old one is removed?
After removing the spring-clip completely, gently wiggled and pulled a little few times. Once the o-ring became visible, it was worry free.
Clean surroundings.
When installing, place the spring-clip first over the adapter at booster. Lubricate the o-ring very lightly then slide the sensor in till it snaps in place. Pull out gently to ensure it is firmly seated.
I always disconnect battery when there is a sensor connect/disconnect – a precaution that JRL often reminds us. Thank you ALL!
