Electronic Throttle Body For Fiat Brava – 46mm – OE71740011 – LOREADA

OE Numbers: 71740011 / 71718821 / 71737116 / 46SXF8

Bore Diameter: 46mm | Direct OEM Replacement | 12+24 Month Warranty | 100% Factory Tested

Vehicle Fitment – Compatible with:

⚠️ Important: This throttle body is designed for Fiat Brava petrol engines with 46mm bore. Diesel variants (1.9 TD, 1.9 JTD) use a different throttle body and are NOT compatible. Engine codes: 1.4L (182.A.000), 1.6L (182.A4.000), 1.8L (182.B6.000). Brava chassis code: Type 182. Please verify your original OE number before ordering.

ℹ️ OE Note: 71740011 is the primary Fiat OE number for this throttle body. 71718821, 71737116, and 46SXF8 are equivalent/cross-reference numbers for the same assembly. All four numbers refer to the same 46mm throttle body for Brava 1.4L/1.6L/1.8L petrol engines.

OE Cross Reference – Match with your original part:

ℹ️ *This throttle body is widely cross-referenced across multiple aftermarket brands including Lucas (LTH5074), CI (XPOT488), Intermotor (68538), Lemark (LTB236), and Fuel Parts (TB3164), all referencing the same Fiat OE specification.*

Technical Specifications

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.

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

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):

• Remove intake sleeve with resonator

• Release accelerator cable terminal from lever

• Disconnect engine idle speed actuator connector

• Remove four retaining bolts

• Reverse to refit

How to Ensure You Get the Correct Part

1. 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.

2. Check your original part number on the existing throttle body – look for 71740011 or 71718821.

3. Verify the throttle bore diameter is 46mm.

4. Match your OE number with our list above.

5. 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.
