Brake Booster Vacuum Sensor Replacement Service & Cost

What is the Brake Booster Vacuum Sensor all about?

Brake boosters or power brakes use a vacuum to generate the additional force needed for efficient braking. The internal combustion engine in cars provide the vacuum with what it needs for the brake boosters to function.

Most internal combustion engines come with an engine control system that senses situations where there is low workload and the engine will not operate on all eight cylinders. This system deactivates some of the cylinders for fuel conservation in the Displacement on Demand or DOD mode. However, an engine in the DOD mode might not provide sufficient vacuum to the brake booster.

The brake booster vacuum sensor is a single chip device that manufacturers fit onto the electrical control unit of the brake booster. This device monitors the vacuum in the brake booster and ensures that there is a sufficient vacuum. If the vacuum levels fall below optimum levels, the brake booster vacuum sensor sends a signal to the engine and deactivates the DOD mode. Once activated, the engine can once again create sufficient vacuum for the brake boosters to function.

The brake booster vacuum sensor might also send a signal to the brake booster vacuum pump and activate it to raise the levels of vacuum. In case there is a leak in the vacuum air line or pipe, the sensor detects this as well.

Keep in mind:

  • If the brake booster vacuum sensor is not operating properly, it will not allow the engine to transition from the DOD to the activated mode. The engine could fluctuate between the two modes. Thus, there are low levels of vacuum.
  • The supplemental brake assist system in your car works to correct the vacuum issue. If it is unsuccessful, you will see the Service Brake Booster message on the dashboard.

Our recommendation:

It is advisable to keep your power brakes or brake booster working in perfect condition for effective braking when driving on the road. If you see the Reduced Brake Power and Service Brake Booster indicators on your dashboard, you should book an appointment with one of our expert mechanics right away. These indicators are a signal that the brake booster vacuum sensor is not working and is unable to correct the vacuum issue in the brake booster. Have the entire brake booster system checked if you need to use excessive force when braking.

What common symptoms indicate you may need to replace the Brake Booster Vacuum Sensor?

  • Reduced Brake Power message comes on the dashboard
  • Service Brake Booster message light comes on

How important is this service?

Not having an efficient and properly working braking system can be a safety hazard when driving. Have the issue inspected and fixed as soon as possible.

Michael was very professional, called me one day before the appointment to make sure everything was on track. He showed up on time to the appointment with a professional appearance and tools. My car was inoperable upon his arrival and helped me push my 3800 lbs vehicle all the way into the apartment complex. He began inspecting the starter that needed replacement and discovered the previous mechanic had not seated the electrical wiring properly and thus the starter did not need be replaced. Most mechanics would of pulled a shady move and still went ahead and replaced it. Due to his findings he was able to save me money and time! I can't wait to work with him again.

Brandon
10 years of experience
Overall I had a good experience with Brandon as My Mechanic. I used this service to diagnose a problem with my 2000 GMC Jimmy in which Brandon ended up diagnosing the problem as a bad fuel pump. Unfortunately, replacing a fuel pump isn't a repair he offered on site which was one major downside and flaw with this service. I think Your Mechanic has a great idea to have the mechanic come to you and is why I went this route to begin with, but when your repair isn't offered on site it really defeats the whole purpose because if your car isn't running you can't drive it to where they need it and i was using this service to avoid tow fees to begin with, and on top of that when you can't have the repair done you lose the perk of using your diagnosis fee towards the repair, so I was really disappointed in that aspect. Brandon was an affable, punctual, and most of all knowledgeable mechanic whom I would recommend to others if what is wrong with your vehicle is an on site fix. He even gave me a way to contact him personally in case his diagnosis was wrong. I have yet to have the repair done, but I am confident that the fuel pump is and was the problem with my truck. Another plus was that he explained to me how he came to that conclusion by telling me his thought process along with showing me the supporting evidence of each step. He also looked over my engine to inform me of some other minor problems with my truck.
