7701044743 Throttle Position Sensor 7714824 9945634 9950634 For Alfa Fiat Ferrari VW Mercedes Benz

7077710 Throttle Position Sensor 7714824/9945634/9950634/7701044743 For Alfa Romeo / Fiat / Lancia / Ferrari / Renault / Dacia / Vw / Mercedes-benz

The sensor operates by detecting the throttle valve position and converting mechanical rotation into an electrical signal. The signal voltage varies proportionally with throttle opening, providing the ECU with continuous, real-time data for fuel injection and ignition timing adjustments. The anticlockwise rotation direction ensures compatibility with the throttle shaft orientation in the designated vehicle applications.

The Throttle Position Sensor 7077710 is an Original Equipment (OE) number used by multiple automotive manufacturers. It is identified by the following OE reference numbers and cross-references:

Manufacturer OE References:

• ALFA ROMEO: 7077710

• FERRARI: 7077710

• FIAT: 7077710

• LANCIA: 7077710

Common Reference Designations:

The Throttle Position Sensor 7077710 is designed for compatibility with a wide range of vehicles across multiple automotive manufacturers.

Important Compatibility Notes:

• This sensor is an Original Equipment (OE) number for ALFA ROMEO, FERRARI, FIAT, and LANCIA vehicles

• Compatible with both manual and automatic transmission variants

• These brands commonly use this part number for various models, particularly in vehicles from the 1980s to 2010s with electronic throttle control systems

• Always cross-check the OE reference number against the number found on your current unit to ensure proper fitment

• Fitment data is sourced from TecDoc, the industry-standard European automotive parts database

A failing or malfunctioning Throttle Position Sensor can produce a range of drivability issues. Below are the most common symptoms to watch for:

One of the earliest indicators of a TPS problem is the illumination of the Malfunction Indicator Lamp (Check Engine Light) on the dashboard. Common diagnostic trouble codes (DTCs) associated with TPS failure include:

• P0120 – Throttle/Pedal Position Sensor/Switch "A" Circuit Malfunction

• P0121 – Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance

• P0122 – Throttle/Pedal Position Sensor/Switch "A" Circuit Low Input

• P0123 – Throttle/Pedal Position Sensor/Switch "A" Circuit High Input

In some Ford vehicles, drivers may also be confronted with the illumination of an amber "Wrench Light" alongside or instead of the standard Check Engine Light, specifically denoting a severe failure within the Electronic Throttle Control (ETC) system.

The most common symptom of a faulty TPS is hesitation whenever the accelerator is pressed. The vehicle may jerk or stumble because the malfunctioning sensor fails to send proper throttle position data, causing an imbalance in the air-fuel mixture needed for smooth acceleration.

A faulty TPS can cause the engine idle speed to fluctuate unpredictably. The idle may be too high or too low, leading to rough idling or "hunting" RPMs.

Since the ECU relies on throttle position data to determine the correct air-fuel ratio, a defective sensor may cause incorrect fuel trims, leading to poor fuel consumption or emissions issues.

The engine may stall unexpectedly—particularly when stopping or at idle—as the ECU receives incorrect throttle position signals and fails to maintain proper air or fuel delivery.

The throttle may become unresponsive or delayed when the accelerator pedal is pressed. This occurs because the ECU is not receiving accurate position data to adjust fuel delivery and ignition timing accordingly.

The vehicle may experience surging or "bucking" while accelerating, as the ECU receives fluctuating throttle position signals.

A malfunctioning TPS can cause harsh, delayed, or erratic shifting in automatic transmissions. The ECU uses TPS data as one of the inputs for shift timing; incorrect data can lead to aggressive or late shifts.

• Wear and tear – Internal potentiometer tracks wear over time due to repeated throttle movements

• Carbon buildup – Excessive carbon deposits on the throttle body can cause the sensor to stick or provide inaccurate readings

• Physical damage – Impact or mechanical stress can damage the sensor housing or internal components

• Corroded or damaged wiring – Wiring issues leading to the TPS can cause intermittent faults

• Loose or poor connection – Poor connection between the TPS and ECU can lead to inaccurate signals

When sourcing or purchasing the Throttle Position Sensor 7077710, consider the following factors to ensure optimal performance and compatibility:

Always confirm that the part number on your existing sensor matches 7077710. Related numbers include 7714824, 9945634, 9950634, 0279983851, and 7701204055. Cross-check the OE reference number against the number found on your current unit before purchasing. The part number will appear on the component itself.

Ensure the sensor is compatible with your specific vehicle make, model, year, engine size, and transmission type. This sensor is primarily designed for ALFA ROMEO, FERRARI, FIAT, LANCIA, RENAULT, DACIA, and VOLKSWAGEN vehicles. Selecting the wrong sensor can lead to poor engine response or persistent check engine light issues. Use the vehicle selector to narrow by model and engine for confirmed fitment.

Verify that the sensor features a 3-pin oval connector and operates with anticlockwise rotation. Confirm that the operating voltage is 12V.

Confirm that the connector type and pin configuration match your vehicle's wiring harness. This sensor features an oval 3-pin connector with 2 mounting bores and is supplied without cable.

Look for sensors constructed with durable automotive-grade ABS plastic material. High-quality sensors are built to the same dimensional and material standards as the original part they replace, ensuring reliable performance and a long service life.

Prioritize products that meet or exceed OEM standards. Parts that match the same OE specification used by the vehicle manufacturer ensure proper fit and function. Fitment data should be sourced from industry-standard databases such as TecDoc.

When sourcing from suppliers, evaluate their quality assurance processes and production capacity. Look for evidence of:

• Strict quality control standards meeting OEM specifications

• 100% factory testing

• Full manufacturer traceability

• Warranty coverage

The sensor features a compact design with 2 mounting bores for secure installation. The sensor is supplied without cable, so ensure the existing wiring harness connector is in good condition. During installation, ensure that:

• The sensor is properly aligned with the throttle shaft

• Mounting screws are tightened to the correct torque specification

• The connector is securely fastened (3-pin oval connector)

• Sensor wires are not routed over sharp edges

• Proper clearance is maintained from ignition HT leads, coil leads, and other sources of electrical interference

After installation, it is recommended to verify the sensor operation using a diagnostic scan tool. Check that the throttle position readings are smooth and consistent throughout the full range of throttle movement and that the warning light is no longer illuminated.

Consider products that come with warranty coverage and technical support. A warranty can provide assurance of product quality and reliability.
