Genuine Throttle Potentiometer | Renault Twingo R2, Clio R3, Cup

The severe risks of running a worn throttle position sensor: what your race engine loses

Motorsport engines developed by the Renault Sport division, whether naturally aspirated or turbocharged, require absolute precision regarding fuel injection and ignition timing data. Retaining a worn or fatigue-weakened angular sensor instead of installing the premium potentiomètre papillon Twingo R2, Clio R3 et X85 Cup immediately compromises communication with your standalone Magneti Marelli or factory ECU. Under the harsh harmonic vibrations of high-rpm operation, the internal resistance tracks degrade. You lose linear acceleration scaling, experience hesitation when flat-shifting out of heavy braking zones, and risk catastrophic engine misfires on your performance car. Ignoring these warning signs inevitably leads to an unexpected DNF in the middle of a special stage or during an official one-make cup race.

This authentic potentiometer sourced straight from the Renault Sport catalog guarantees ultra-precise tracking of the throttle butterfly shaft, engineered to withstand fuel vapor exposure, high engine bay temperatures, and intense motorsport stress.

Precision electrical engineering calibrated for racing throttle bodies

Unlike standard low-cost road car sensors that fail under race-track conditions, this ruggedized replacement potentiometer effortlessly manages constant thermal shock. Its strict electrical output curves supply an instantaneous response time, which is paramount for optimizing launch control algorithms and flat-shift strategy updates. It represents an absolute hardware necessity for the high-end maintenance of your race machine or when upgrading the electronic limits of your track-day sports chassis setup.

Motorsport electronics application and vehicle model compatibility guide

This genuine factory throttle position sensor is engineered specifically for the specialized throttle body assemblies of the following official racing platforms:

• Renault Twingo 2 R2 – Fits all official rally variants, including R2 Evo models utilizing the race-prepared 1.6L K4M Renault Sport engine.
• Renault Clio 3 RS R3 – Fits Rally R3 Access, R3 Maxi, and R3 Evo configurations powered by the high-revving 2.0L F4R naturally aspirated engine.
• Renault Clio 3 Cup (X85) – Fits all official single-make track series race cars manufactured from 2006 to 2013 utilizing the X85 Cup chassis.

Frequently Asked Questions regarding racing throttle position sensors (FAQ)

Is an electronic calibration procedure required after installing this sensor?
Yes. Installing this new potentiometer onto a racing throttle body requires a manual min/max throttle stop calibration via your diagnostic tool or your standalone ECU software to map the 0-100% signal output correctly.

Can this sensor be used on a regular road-going vehicle?
While this component is built to meet the rigorous demands of official Clio Cup and Twingo R2 race cars, it can adapt to modified street cars running the exact same factory-spec mechanical throttle body for track day builds.

Restore absolute throttle precision and protect your competitive lap times

A faulty or erratic potentiometer feeds incorrect data to the engine management system, risking dangerous air-fuel ratios and electrical limp modes. Do not let an unstable electrical signal ruin your competitive efforts on track or stage. Trust the premium motorsport components curated by the Optimiz Access team to secure your drivetrain electronics, and finalize your order for the Throttle Potentiometer Twingo R2 / Clio R3 / Cup today.
