How Much Does It Cost to Fix Electronic Throttle Control?

Most electronic throttle control repairs cost $100–$300 for cleaning or a relearn/calibration, while replacing the throttle body typically runs about $350–$900 on mainstream vehicles and $800–$1,500+ on larger trucks and luxury models, including parts and labor; diagnostics usually add $120–$200 if not applied toward the repair.

What Electronic Throttle Control Is—and Why It Fails

Electronic throttle control (ETC), often called “drive-by-wire,” replaces the old cable between the pedal and throttle plate with sensors, a throttle body motor, and engine computer logic. When sensors disagree or the throttle plate can’t move as commanded, the system may limit power (limp mode) and illuminate an ETC or wrench light. Common culprits include a dirty or failing throttle body, accelerator pedal position (APP) sensor faults, wiring/connectors, and, less often, software or control module issues.

Typical Repairs and National Cost Ranges (Parts + Labor)

The following list outlines the most common ETC-related fixes and what drivers in the U.S. can expect to pay at independent shops or dealerships in 2025, assuming labor rates of roughly $120–$190 per hour.

• Throttle body cleaning and idle relearn: $100–$200 (DIY supplies: $10–$20). Helpful for carbon buildup and sticky plates; some vehicles require a scan-tool relearn.
• Throttle body replacement: $350–$900 on mainstream cars/SUVs; $800–$1,500+ on some trucks and luxury brands. Typical parts $120–$700; book time 0.7–2.0 hours. Many modern units integrate the throttle position sensor, so the whole assembly is replaced.
• Accelerator pedal position (APP) sensor or pedal assembly: $180–$500 installed. Frequently resolved by replacing the entire pedal module.
• Throttle position sensor (if serviceable separately): $160–$400 installed. On many late-model vehicles the TPS is non-serviceable and included with the throttle body.
• Wiring/connector repair (harness chafes, corrosion, broken pins): $50–$400 depending on location and extent; intermittent faults can add diagnostic time.
• Software update or throttle relearn/calibration: $0–$200. Dealer programming or an idle/throttle relearn may resolve logic or adaptation issues after a repair or battery disconnect.
• Engine control module (ECU/PCM) replacement and programming: $700–$1,700+. Rare for ETC faults; includes programming fees ($100–$200).
• Diagnostic fee (scan, live data, pinpoint tests): $120–$200. Often credited toward the repair if you proceed with the same shop.
• Throttle body gasket/coolant top-off: $5–$25 for a new gasket; some vehicles route coolant through the housing, which may require topping off or bleeding.
• Battery/charging system correction (low voltage can trigger ETC codes): $150–$350 for a battery replacement or terminal/ground service.

Final costs vary by vehicle, region, and parts choice (OEM vs. aftermarket vs. reman). Expect shop supplies and taxes on top of quoted figures.

Example Out-the-Door Totals You Might See

The examples below illustrate typical invoices owners report for ETC-related work on common vehicles; your quote will depend on engine, options, and local labor rates.

• 2016 Toyota Camry: Throttle body cleaning + idle relearn — $165–$240.
• 2018 Ford F-150 5.0L: Throttle body replacement — $520–$900.
• 2015 Jeep Grand Cherokee: APP sensor/pedal assembly — $260–$480.
• 2012 Hyundai Elantra: Connector repair and corrosion cleanup — $140–$320.
• 2019 BMW X5: Throttle body replacement — $950–$1,450.

These ranges are representative but not definitive. Use your VIN when seeking quotes to confirm part numbers and labor times.

What Drives the Price

Several factors determine what you’ll pay to resolve an ETC fault. Understanding them helps interpret quotes and decide between repair options.

• Vehicle and engine design: Some throttle bodies are simple; others integrate multiple sensors and require replacement as a unit.
• Labor rate and book time: Urban areas and dealerships tend to charge more; access can add time on tightly packaged engines.
• Parts strategy: OEM parts usually cost more than aftermarket or remanufactured units but may include updated designs.
• Calibration needs: Many vehicles require a scan-tool relearn after cleaning or replacement, adding time and possible programming fees.
• Related work: Gaskets, coolant bleed, carbon-heavy intakes, or brittle hoses can increase the total.
• Warranty, recalls, and TSBs: A technical service bulletin (TSB) or extended warranty can reduce or eliminate your cost if your vehicle qualifies.

Ask for a line-item estimate showing diagnostics, parts, labor hours, programming, and shop fees; then verify whether a TSB or goodwill coverage applies.

Symptoms That Point to ETC Service

ETC issues often present with a mix of warnings and drivability changes that differ from classic vacuum or cable-related problems.

• ETC/wrench light or check-engine light illuminated (sometimes both).
• Limp-home mode with reduced power or fixed idle speed.
• Hesitation, surging, unstable idle, or stalling at stops.
• Delayed or inconsistent throttle response from a steady pedal.
• Diagnostic trouble codes like P0121–P0123, P0222–P0229, P2101, P2110, P2111, P2112, P2135, P2138.

A proper diagnosis includes scanning for codes, reviewing freeze-frame data, and observing live sensor agreement (APP vs. throttle angle) before replacing parts.

Can You Keep Driving With the ETC Light On?

If the vehicle enters limp mode or stalls, pull over safely and consider a tow; power may be limited and merging can become hazardous. If the light is on but drivability is normal, you may be able to drive short distances to a shop, but continuing to operate the vehicle risks sudden power loss and traffic exposure. Address ETC warnings promptly.

DIY vs. Professional Repair

Some ETC fixes are approachable for experienced DIYers, but modern systems are sensitive to handling and calibration.

• Cleaning: Manageable with throttle-body-safe cleaner; avoid forcing the electronic plate. Expect to perform an idle or throttle relearn procedure afterward.
• Sensor replacement: Feasible when accessible, but many sensors are integrated; incorrect installation or missed calibration can worsen drivability.
• Full throttle body replacement: Requires correct torque, new gasket, and often a scan-tool relearn; best for pros if you lack the tools.

When in doubt, pay for a diagnostic first—guessing at ETC parts can be costly and may not solve root causes like wiring faults or low system voltage.

Ways to Save on an ETC Repair

Before authorizing work, consider these steps to reduce costs without compromising reliability.

• Check for recalls, extended coverage, or TSBs; some brands have known throttle body or APP issues with updated parts or goodwill assistance.
• Compare quotes from a dealership and a reputable independent; ask about OEM vs. reman parts with warranty.
• Bundle maintenance: Replace a clogged air filter and clean the throttle body during scheduled service to prevent buildup.
• Protect system voltage: A healthy battery and clean grounds help prevent false ETC codes and relearn issues.
• Use the right cleaner: Some coated throttle bodies require specific products; the wrong solvent can damage the finish and sensors.

Document symptoms and codes, request the old part back when possible, and ensure the estimate includes any needed programming or relearn.

Warranty and Coverage Notes

Factory coverage often includes 3 years/36,000 miles bumper-to-bumper and 5 years/60,000 miles powertrain; throttle bodies may fall under either depending on the brand. Emissions warranties (up to 8 years/80,000 miles for certain components) sometimes cover related electronics, but coverage is vehicle-specific. Extended service contracts typically cover throttle bodies and pedal assemblies, subject to deductibles. Always check by VIN.

Bottom Line

Expect $100–$300 for cleaning or calibration-based fixes and $350–$900 for a throttle body replacement on most vehicles, with $800–$1,500+ possible on higher-end models. Sensors and wiring repairs commonly land between $160 and $500. Start with a proper diagnostic, verify any TSBs or coverage, and insist on a relearn or software update when required to avoid repeat visits.

Summary

Fixing an electronic throttle control issue typically ranges from a low-cost cleaning and relearn to a higher-ticket throttle body replacement. Most mainstream vehicles see totals of $350–$900 for replacement, while simple services or sensor repairs can resolve many cases for under $300. Accurate diagnosis, checking for bulletins or coverage, and confirming calibration steps are the keys to paying only for the repair you actually need.

Is electronic throttle control expensive to fix?

Electronic throttle control (ETC) repairs can be expensive, with replacement costs for a faulty throttle body ranging from $70 to over $1,000, depending on the vehicle’s part cost and labor rates in your area. A simple cleaning might be a cheaper fix, but a complete throttle body replacement is the most common repair for ETC issues, and labor costs, diagnostic fees, and the need for a special “re-learn” procedure on some vehicles can add to the expense.
 
Factors influencing cost:

• Diagnostic fees: Mechanics must run diagnostics to pinpoint the exact issue, which can be costly. 
• Parts cost: The price of the new throttle body itself varies significantly by make and model. 
• Labor rates: These hourly charges from the repair shop differ based on your location and the specific mechanic. 
• “Re-learn” procedure: Some vehicles require a special electronic re-learn procedure after a throttle body replacement, which adds to the labor time and cost. 

What you can expect:

• Cleaning: A simple cleaning of a dirty throttle body can be a low-cost solution. 
• Replacement: If the throttle body needs to be replaced, the total cost combines the part and labor. For example, a 2014 Chrysler 200 throttle body replacement can range from $472 to $522, while costs for other vehicles can be significantly different. 
• Other repairs: The problem might stem from a cheaper part, like a throttle position sensor, rather than the entire throttle body. 

To get a more accurate estimate:

• Get multiple estimates: Contact several mechanics for quotes based on your specific vehicle. 
• Provide details: Be prepared to provide details about your vehicle’s make, model, and year to get the most accurate estimate. 
• Ask about the re-learn procedure: Inquire if the repair will include the electronic re-learn procedure, which can add to the total cost. 

How do I fix my electronic throttle control warning?

To fix a throttle control warning light, you typically need to address carbon buildup in the throttle body, faulty throttle position sensors, or electrical issues. First, check for Diagnostic Trouble Codes (DTCs) with an OBD-II scanner to get a specific diagnosis. Then, you can attempt a throttle body “relearn” or reset procedure, often by cycling the ignition key and pressing the accelerator pedal. If the light persists, cleaning the throttle body and inspecting wiring and sensors are the next steps. If the problem continues, a professional mechanic should replace the faulty part.

Step-by-Step Fixes

1. Scan for Codes: Use an OBD-II scanner to read diagnostic trouble codes (DTCs), which will point to the specific issue. 
2. Perform a System Reset/Relearn: After a battery change or a loose connection, a reset procedure might be necessary. 
   • Turn the ignition to the “ON” position without starting the engine. 
   • Slowly press and hold the accelerator pedal to the floor for about three seconds. 
   • Release the pedal slowly. 
   • Repeat this process two more times. 
   • Turn the ignition off and wait for about 10 seconds before starting the engine. 
3. Clean the Throttle Body: Carbon buildup can cause the throttle plate to stick. 
   • Locate the throttle body and the air intake duct. 
   • Remove the air intake duct. 
   • Use a specialized throttle body cleaner to spray the inside of the throttle body, focusing on the plate, to remove any deposits. 
   • Reinstall the air duct securely. 
4. Inspect Wiring and Sensors: Check the throttle position sensor (TPS) and accelerator pedal sensor for any signs of damage, corrosion, or loose connections. 
5. Replace Parts: If cleaning and resetting don’t work, you may need to replace the throttle position sensor, the throttle body assembly, or the accelerator pedal sensor. 
6. Seek Professional Help: If you’re unable to resolve the issue, take your vehicle to a licensed mechanic for a thorough diagnosis and repair. 

What causes electronic throttle body failure?

One of the main causes of a malfunctioning throttle body is internal contamination. Due to the contamination accumulated in the throttle body, the throttle valve can no longer move properly, causing problems with the control of the air supply.

Can you drive with a bad electronic throttle control?

No, driving with a flashing electronic throttle control light is not recommended. It signals a serious issue with the electronic throttle control system, and continuing to drive could damage the engine or lead to a sudden loss of power.
