How much does it cost to get a throttle body cleaning?

Most drivers pay roughly $60 to $200 for a throttle body cleaning, depending on whether it's a simple spray with the unit in place or a full removal and deeper cleaning. In high-cost markets or at a dealership, prices can be higher.

Beyond the price tag, the service targets buildup on the throttle body and related sensors to restore smooth idle and throttle response. Costs vary by vehicle, region, and the level of service—from a quick clean to an extensive job that may include gasket replacement or sensor work. This article outlines typical price ranges, factors that influence those costs, and DIY versus professional options.

Typical price ranges for throttle body cleaning

The following ranges reflect common quotes from independent shops, chains, and dealerships, and cover different levels of service from a quick clean to a more involved procedure.

• Basic cleaning (no removal of the throttle body; spray-down and surface cleaning): typically $60–$100.


• Standard cleaning (more thorough internal cleaning and possible IAC valve checks; may involve partial removal): usually $100–$180.


• Comprehensive service (throttle body removal, gasket replacement, cleaning of related components such as sensors): commonly $180–$350 or more.

Prices can vary by location, vehicle, and shop. Some shops also charge a diagnostic or shop fee, so it’s wise to confirm what the quote includes before authorizing work.

What factors influence the price

Several elements determine the final cost of throttle body cleaning beyond the basic service level.

• Location and shop type (urban markets and dealerships tend to be more expensive than rural independents).


• Vehicle design and engine type (direct-injection or turbocharged engines can require more labor and care).


• Scope of work (whether removal is required, gasket replacement, or cleaning of adjacent sensors).


• Labor rates and potential diagnostic fees (some shops bundle these into the service, others itemize).


• Promotions, warranties, and parts quality (OEM vs aftermarket gaskets and seals).

Because prices vary widely, always request a written quote that breaks down labor, parts, and any additional fees. This helps prevent surprises and ensures you know exactly what you’re paying for.

Vehicle design and labor considerations

Direct-injection engines, turbocharged setups, and vehicles with tight intake plumbing can require more time and care to access and properly clean the throttle body. In some cases, removal is necessary, adding to both time and cost.

Labor rates and regional differences

Labor rates differ by region. A shop in a major city or at an authorized dealership will typically bill more per hour than a rural independent, which can push the overall price toward the higher end of the ranges above.

DIY vs professional service

For mechanically inclined users, a do-it-yourself throttle body cleaning can save money, but it carries some risk if sensors or gaskets are damaged or miscalibrated.

• DIY materials: throttle body cleaner or spray, new gasket if removal is involved, rags, and basic hand tools. Expect about $10–$50 in supplies.


• Professional service benefits: expert cleaning, any necessary sensor or gasket replacements, and a warranty on workmanship and parts.


• Time considerations: a basic clean can take 30–60 minutes; a more involved job may take 1–2 hours or longer depending on access and vehicle complexity.

Before attempting a DIY cleaning, consult your vehicle’s service manual and consider whether the throttle body or idle air control valve (IAC) requires special calibration after cleaning. If uncertain, a professional service provides peace of mind and helps ensure proper idle and throttle response.

What to ask before agreeing to throttle body cleaning

• What exactly is included in the quoted price (labor, parts, diagnostic fees, taxes)?


• Is throttle body removal required, and are gaskets or sensors included in the price?


• Will the service affect other systems (idle control, MAF sensor) and require calibration or retraining?


• Is there a warranty on workmanship and parts, and what does it cover?

Being clear about scope and expectations helps you avoid surprises and ensures you receive the service you need.

Summary

Throttle body cleaning generally costs between about $60 and $350, depending on service level, vehicle, and location. Basic spray-downs are the least expensive, while removal-based cleanings and gasket or sensor work push the price up. DIY approaches can save money but carry risk; for many drivers, a professional service offers reliability and a warranty. Always get a written, itemized quote and ask about warranties to make an informed decision that restores idle quality and throttle response without overpaying.

How often does a throttle body need to be cleaned?

A throttle body should be cleaned every 25,000 to 75,000 miles, depending on the vehicle and driving conditions, or as recommended in your owner's manual. You can also perform this maintenance when you notice symptoms like a rough idle, poor acceleration, or hesitation, or as a preventative measure during regular service like an air filter change. 
Cleaning intervals

• Every 25,000 to 30,000 miles: A common recommendation for regular cleaning to ensure optimal performance. 
• Every 40,000 to 75,000 miles: Some experts and manufacturers suggest this longer interval, sometimes aligning with major tune-ups. 
• At specific mileages: Some models, like a Prius, may benefit from cleaning every 25,000 miles to address carbon buildup. 

When to clean your throttle body

• When you notice performance issues: Rough idling, hesitation, poor acceleration, or stalling can all be signs of a dirty throttle body. 
• During other maintenance: It's a good time to check and clean the throttle body when you are changing the air filter. 
• As a preventative measure: Even if you don't have issues, regular cleaning can prevent future problems, especially if you do a lot of stop-and-go driving. 

Important considerations

• Check your owner's manual: It is the best source for a specific cleaning recommendation for your vehicle. 
• Be cautious with electronic throttle bodies: Do not manually force the throttle plate open on an electronic throttle body, as this can cause damage. Consult a professional if you are unsure. 
• Inspect for buildup: If the throttle body appears black or has gummy deposits, it is time to clean it. 

Is cleaning your throttle body worth it?

Yes, cleaning the throttle body makes a difference by improving engine performance, including a smoother idle, better acceleration, and increased fuel efficiency. A dirty throttle body can cause issues like rough idling, poor acceleration, and stalling because grime and buildup disrupt the proper flow of air into the engine.

How it makes a difference

• Smoother idle: A buildup of carbon and grime can cause the engine to idle unevenly or rough. Cleaning it restores the correct airflow, resulting in a smoother idle. 
• Better acceleration: Grime can restrict the amount of air entering the engine, leading to sluggish or slow acceleration. Cleaning the throttle body allows for a more direct path for air, improving throttle response. 
• Improved fuel economy: With a cleaner throttle body, the engine can achieve the optimal mix of air and fuel for combustion, which can lead to better fuel efficiency. 
• Prevents stalling: By ensuring consistent airflow, cleaning the throttle body helps prevent stalling that can occur from air/fuel mixture problems.
