Throttle Body Replacement Cost: What You Will Pay in 2026

Throttle body replacement cost usually falls between $250 and $1,000 for most cars, including parts and labor, based on sources checked as of 2026-11-06. The total depends on your vehicle, the part you choose, and your shop’s labor rate.

Part price and labor rate matter more than anything else in the throttle body replacement cost. Confirm the fault with a diagnosis first, because a rough idle does not always mean the throttle body is the cause.

How Much Does a Throttle Body Replacement Cost?

For most cars, a throttle body replacement costs $500 to $650, according to Synchrony, while Jerry puts the typical range at $300 to $1,000 as of 2026-11-06. Synchrony notes some jobs cost under $200 and others reach $1,000 or more, based on its blog post published September 18, 2024. Jerry’s guide, dated January 9, 2025, bases its range on the part and the labor rate.

VehicleRuns, updated June 24, 2026, gives a typical total of $250 to $800 and says everyday vehicles land at $350 to $600. MechanicRank, written by a working mechanic and updated October 11, 2026, lists $255 to $800 at independent shops, with parts at $180 to $550 and 0.8 to 1.8 hours of labor. These four are consumer advice sites rather than repair shops, so read their figures as estimates.

Parts are the largest share of the bill, which is why the part you choose affects the total most. Labor is smaller, so a lower labor rate helps less than a cheaper part.

As a simple sum of Jerry’s figures, a $256.99 aftermarket part plus 1 hour of labor at $110 per hour comes to about $367 before tax and diagnosis. The $382.91 Ford Parts unit plus 2 hours at $175 per hour comes to about $733, so the all-in range is wide.

What Drives the Price of a Throttle Body Replacement

Vehicle type and part source move the throttle body replacement cost more than anything else. Large or luxury vehicles use pricier throttle bodies, and the cost of the part sets most of the bill.

• Vehicle size and class: large or luxury cars have higher-priced units (Synchrony).
• Part source: OEM units cost more than aftermarket units (Synchrony and Jerry).
• Labor rate: each shop sets its own hourly rate, and Jerry reports $110 to $175 per hour across the U.S. for the throttle body replacement cost.
• Diagnosis: a mechanic may spend hours confirming that the throttle body is the fault (Synchrony).

OEM vs Aftermarket Throttle Body Prices

An OEM throttle body costs more than an aftermarket unit, so the part you choose changes the total a lot. On a 2015 Ford F-150 5.0L, the gap is about $126, based on Jerry’s price examples for the same engine.

These are part prices only, so the full throttle body replacement cost also includes labor, diagnosis and any programming. Synchrony suggests asking your mechanic whether an aftermarket part can save money, and checking the fit for your exact model.

Jerry also lists a BMW 550i GT OEM unit at $218.99 from FCP Euro. VehicleRuns puts a basic aftermarket unit at $150 to $300 and an OEM part for a newer vehicle at $350 to $550 or more.

The examples above are from one model year and a few sellers, so they show the spread in throttle body replacement cost rather than a fixed price. Prices for your exact engine and year may be higher or lower, and a shop quote is the only reliable figure for your car.

Labor Time, Shop Rates and Repair Steps

The job usually takes 1 to 2 hours, so labor adds about $110 to $350 to the throttle body replacement cost at typical U.S. shop rates of $110 to $175 per hour, as of 2026-11-06. Synchrony puts labor closer to $100, so the spread between shops can be wide.

Labor is a smaller share of the throttle body replacement cost than parts. VehicleRuns puts labor at $100 to $250 and a shop rate at $100 to $180 per hour. Jerry describes the replacement as possible but sometimes complicated, depending on make and model, which is another reason the throttle body replacement cost varies.

When you compare quotes, check whether the labor hours cover diagnosis, the replacement and any programming. Synchrony notes that a diagnosis can take hours, and Jerry says programming may need specialist tools. VehicleRuns lists relearn or programming at $0 to $100, depending on the vehicle, so ask which of these the quote includes. For a sense of which tools can run that step, see scanners that perform a throttle relearn.

Signs a Throttle Body Needs Replacing

Common signs of a failing throttle body include rough idle, stalling and slow acceleration, often with a check engine light. Synchrony and Jerry list the same core symptoms, and a guide to why a car shakes at idle covers the idle side of the problem.

• Rough idling, including shaking or vibration while in park
• Stalling or loss of power
• Engine misfires
• Jerking or shaking during gear changes
• Slow or less responsive acceleration
• Lower fuel economy than usual
• A check engine light

Synchrony notes that a mechanic may need hours to confirm the throttle body is the fault, so ask about diagnosis early, since that time adds to the throttle body replacement cost. VehicleRuns lists a diagnostic fee of $75 to $150 if it is not waived when you approve the repair, so ask about that fee early. Jerry also mentions hissing, whistling or humming noises. Synchrony suggests replacing the unit when symptoms appear or around 100,000 to 150,000 miles, and cleaning it every 75,000 to 90,000 miles.

How an Electronic Throttle Body Works

An electronic throttle body uses a DC motor to open a valve, and two position sensors report the valve angle to the engine computer. According to the NASA report prepared for NHTSA from 2011, the motor drives the valve through reduction gears, and the control module sets the opening.

When the motor has no power, two return springs hold the valve at a fixed position about 6.5 degrees from fully closed. The report says this lets the engine run slightly above idle when the motor is unpowered.

The module compares the two sensor signals to detect sensor problems. The engine control module also contains two CPUs, and both must agree that the engine is operating properly, according to the same report. This is why a throttle body is an electronic assembly rather than a simple valve, which helps explain the throttle body replacement cost.

The NASA report also lists a fail-safe mode for a throttle sensor or motor failure. In that mode the throttle motor is disabled and the throttle is held at its spring detent position.

Should You Replace a Throttle Body Yourself?

Replacing a throttle body yourself is possible, but Jerry calls it complicated and advises a professional without the right experience and tools. Synchrony agrees and recommends a professional, noting that the throttle body replacement cost is mostly parts.

• The procedure can be complicated, depending on make and model (Jerry).
• Many modern units need reprogramming, which may need specialist tools (Jerry).
• Parts are the largest expense, so doing the labor yourself saves less than expected (Synchrony).
• VehicleRuns estimates that skipping shop labor saves $100 to $250, which is a smaller saving than the part itself.
