Technical Specifications
| Parameter | Specification |
|---|---|
| Design | 100% OEM specification – direct replacement |
| Product Type | Electronic Throttle Body / Throttle Valve Assembly |
| Throttle Bore Diameter | 46 mm |
| Connector Type | Oval (4-pin / multi-pin – verify with original) |
| Housing Material | Die-cast Aluminum Alloy + Anti-corrosion Surface Treatment |
| Butterfly Valve Material | Stainless Steel |
| Seal Material | Oil-resistant Fluorine Rubber (Viton) |
| Fuel Type | Petrol / Gasoline (Naturally Aspirated) |
| Weight | Approx. 0.86 kg |
| Voltage | 12V |
| Operating Mode | Electric |
| Heating Function | Coolant-heated throttle body (prevents icing in cold/humid conditions) |
| Warranty | 12 months (general) / 24 months (motor & sensors) |
ℹ️ The throttle body meters air intake according to accelerator pedal position. The butterfly is opened via linkage. At idle/deceleration, the idle speed actuator supplies additional air. The throttle body is heated by recycling engine coolant to prevent ice formation in cold/humid conditions.
Product Highlights
✅ OE Fitment – Developed to strict OEM standards. Direct replacement – no wiring modification required.
✅ Brava Optimized – Specifically engineered for Fiat Brava 1.4L, 1.6L, and 1.8L petrol engines.
✅ Plug & Play Installation – Exact match in dimensions, mounting bolt pattern (4 bolts), and intake manifold fitment.
✅ High Performance – Motor response time ≤ 50 ms for precise intake control, smooth acceleration, and improved throttle sensitivity.
✅ Reliability – Integrated idle speed actuator and throttle position sensor for stable idle and consistent performance.
✅ Rigorous Testing – 100% factory-tested for thermal cycling, airtightness, and full-stroke angle calibration.
✅ Anti-Icing Protection – Coolant heating circuit prevents throttle plate freezing in cold weather conditions.
✅ Standard Compliance – Meets ISO 16750 environmental standards for automotive electrical/electronic equipment.
✅ Wide Aftermarket Support – Cross-referenced with multiple trusted brands including Lucas, CI, Intermotor, and Lemark.
Common Symptoms of a Failing Throttle Body (Fiat Brava)
-
Unstable idle, "hunting," or engine stalling at stops
-
Hesitation or flat spot during acceleration
-
Poor throttle response / delayed acceleration
-
Check Engine Light (CEL) – common DTCs may include throttle position sensor or idle actuator faults
-
Rough idle that improves when throttle is applied
-
Poor fuel economy
-
Cold start issues (especially in humid/cold conditions if heating circuit fails)
These symptoms are frequently reported for high-mileage Brava vehicles when the throttle body components wear out.
Installation & Adaptation Tips
IMPORTANT: After replacing the throttle body on Fiat Brava, a throttle self-learning / idle relearn procedure is REQUIRED using a diagnostic tester
| Step | Action |
|---|---|
| 1 | Disconnect the negative battery terminal for 5 minutes (clears old learned values). |
| 2 | Install the new throttle body with a new gasket. Torque the four retaining bolts evenly. |
| 3 | Reconnect the accelerator cable to the lever (A) and secure the adjustment block to bracket (B). |
| 4 | Reconnect the battery and all electrical connectors (including engine idle speed actuator connector). |
| 5 | Turn ignition ON (do not start engine) and wait 10 seconds. |
| 6 | Turn ignition OFF for 10 seconds. |
| 7 | Connect a diagnostic tester (e.g., Examiner) to the tester connection and run the required procedure to zero and self-learn engine idle adjustment actuator (M.D.S.) data. |
| 8 | Start the engine and let it idle for 5 minutes (do not touch accelerator). |
| 9 | Turn engine off for 30 seconds, then restart and drive normally. |
For Fiat Brava 1.4/1.6/1.8: The ECU will complete adaptation after the tester procedure. Do not skip the diagnostic relearn step – it is essential for proper idle control. After replacement, it may take a few drive cycles for the ECU to fully adapt.
Throttle Body Removal Notes (per Fiat Service Manual):

How to Ensure You Get the Correct Part
-
Confirm your vehicle is a Fiat Brava (Type 182) with 1.4L, 1.6L, or 1.8L petrol engine. Diesel variants (1.9 TD/JTD) are NOT compatible.
-
Check your original part number on the existing throttle body – look for
71740011or71718821. -
Verify the throttle bore diameter is 46mm.
-
Match your OE number with our list above.
-
Contact us with your VIN or a photo of your original part if unsure.
⚠️ Important: This throttle body is designed for petrol engines ONLY. Diesel Brava models require different throttle/intake components and are NOT compatible with this listing.
After-Sales & Disclaimer
-
Pre-installation check: Inspect the throttle body for any defects. Verify the OE number and connector type before installation. A new mounting gasket is strongly recommended.
-
Compatibility: This throttle body is for Fiat Brava 1.4L, 1.6L, and 1.8L petrol engines ONLY. It will NOT fit Brava diesel variants, Brava 2.0L 20V, or other Fiat models (Bravo, Marea, Punto) without verification.
-
Diagnostic requirement: Professional diagnostic equipment (Examiner or compatible tool) is required for proper idle relearn after installation. The simple battery disconnect method may not be sufficient for this vehicle.
-
Gasket requirement: A new mounting gasket is strongly recommended for proper sealing and to prevent vacuum leaks.
-
Warranty: This product carries a 12-month warranty against manufacturing defects. The motor and sensors are covered for 24 months.
