How Long Does a Throttle Body Last?

Throttle Body

There are so many components involved in a vehicle running properly, but some of the main ones are rather basic in their role. The throttle body is one of those parts. This component is part of the air intake system - a system that lends a big hand in controlling the amount of air that is allowed into the engine. Should the throttle body stop working or become faulty, the right amount of air won’t be let in. This affects your fuel consumption in a negative way.

While there is no set mileage when it comes to the lifespan of the throttle body, it is suggested that you give it a thorough cleaning at about 75,000 miles. Cleaning the throttle body allows your car to operate more smoothly and it helps increase its lifespan. Dirt, debris, and grime build up over time which really takes a toll on the throttle body. It’s best to have this cleaning done by a professional mechanic. A fuel injection flush and an air induction service also aids in keeping it clean.

Unfortunately once this part fails it will need to be replaced rather than repaired. So what are the signs to look for? Here are the most common symptoms of a throttle body that has reached the end of its lifespan:

  • Do you seem to have issues with transmission shifting? This can definitely point to a faulty throttle body that needs attention.

  • If you find your car is rough when driving or when idling, again this can be an issue with the throttle body. Since the correct air and fuel mixture isn't being reached, it can even result in a lack of power and just overall poor performance.

  • There may be warning lights such as "Reduced Power" and/or "Check Engine" that come on. Both of these need attention by a professional mechanic so they can diagnose the situation.

The throttle body plays a large role in controlling the fuel and air mixture in your engine. The proper mixture needs to be achieved in order for your engine to run smoothly and properly. Once this part fails, it needs replacing rather than repairing. If you’re experiencing any of the above mentioned symptoms and suspect your throttle body is in need of replacement, have a certified mechanic replace the failing throttle body to eliminate any further problems with your vehicle.
