Throttle Body Replacement Cost: Parts, Labor & Average Price

The throttle body controls how much air enters the engine when you press the accelerator. On most modern cars it is electronic and works with the engine computer. When it fails or clogs with carbon, you may notice a rough or unstable idle, hesitation, stalling, or a check engine light.

Replacement is a parts-heavy job. Prices below were checked on Oct 13, 2026. Before you pay for a new unit, it is worth finding out whether a cleaning or a different part would solve the problem.

Parts make up most of the national estimate, and labor is a smaller share. The split depends on the vehicle, since some throttle bodies are costly electronic assemblies.

Labor time varies with how buried the throttle body is in the engine bay, and some repair guides note that the new unit may need a relearn or adaptation step afterward. Ask whether that step is included in the quote.

The vehicle class shifts the total a lot. Compact cars cost the least, trucks and SUVs sit higher, and luxury and European models cost the most.

For luxury and European cars, totals can reach the top of the table or beyond. Diesel trucks sit in the upper middle because of parts cost and labor time.

The throttle body itself comes in three grades. Original-equipment parts from a dealer cost the most. Remanufactured units, which are rebuilt originals, sit in the middle and may carry a core charge. Quality aftermarket units usually cost the least and carry a warranty.

If you are paying out of pocket on a car outside warranty, a reputable aftermarket or remanufactured throttle body can lower the bill. Ask which type is on the quote and what warranty applies.

Carbon buildup in the throttle body can cause symptoms that look like a failed unit. A professional cleaning costs far less than replacement and sometimes resolves the problem. Cleaning does not help when the electronic part has failed, so a diagnosis comes first.

Ask the shop to scan for codes and inspect the throttle body before agreeing to a replacement. Many shops waive or reduce the diagnostic charge if you have the repair done with them, so ask.

RepairPal's national figure and the Empire Auto Protect range are far apart, and the reasons may include:

• RepairPal's estimate is a national average for replacement, with parts and labor listed separately.
• Empire's range is wider and runs up to luxury and European models, where the part costs more.
• Parts grade matters, since original-equipment, remanufactured, and aftermarket units differ in price.
• Labor rates vary by region and by shop type, and neither estimate uses your zip code.

For a common car, the RepairPal range is a good planning figure. If you drive a luxury or European model, or plan to use a dealer, the upper end of the Empire range is more realistic.

Dealers generally use original-equipment parts and charge higher labor rates, which pushes totals toward the top of the ranges. Independent shops can often fit quality aftermarket or remanufactured throttle bodies and charge less per hour. If your car is under warranty, a failed throttle body may be covered, so check before paying. Get the quote in writing, with the part type and warranty listed.

• Vehicle type. Compact cars, trucks, and luxury models are priced in different bands.
• Throttle body design. Electronic assemblies vary widely in price between makes.
• Part grade. Original-equipment, remanufactured, and aftermarket units differ widely.
• Labor time. A deeply buried unit takes longer to reach.
• Relearn or calibration. Some cars need the computer to learn the new part.
• Diagnosis. A scan and inspection may be billed separately.
• Shop type and region. Hourly rates vary.

A throttle body problem can cause stalling, hesitation, or unexpected changes in engine response, all of which affect how safely you can accelerate and merge. If your car stalls or surges, have it checked promptly by a licensed technician instead of waiting for the next oil change. This page does not cover how to do the repair, and throttle work involves the engine computer and sensors that a qualified shop should handle.
