WJIECO 8200771294 oxygen sensor Downstream Oxygen O2 Sensor Cross DENSO 234-4448 for Renault Clio III Modus Twingo II Kangoo II Gasoline Vehicles

8200771294 Oxygen Sensor Overview

The 8200771294 Oxygen O2 Sensor (Renault OE# 8200771294, cross reference DENSO 234-4448) is an OEM-grade downstream oxygen sensor engineered by WJIECO for gasoline Renault compact passenger cars and light vans. Also known as a post-cat O2 sensor, this exhaust component mounts after the catalytic converter. Its core function is to measure oxygen concentration in exhaust gas exiting the catalyst, enabling the ECU to assess catalytic converter working efficiency. This sensor is essential for emission compliance and catalyst diagnostics on these small-capacity Renault petrol platforms.

This sensor is designed as a direct factory replacement for these applications: Renault Clio III, Renault Modus, Renault Twingo II, Renault Kangoo II.

If your Renault vehicle triggers a persistent check engine light, failed emissions inspection, catalytic converter efficiency codes, or irregular oxygen sensor readings, your factory downstream oxygen sensor is likely suffering from sensing element contamination, signal drift or aging damage. Replacing the defective original sensor with this direct-fit 8200771294 replacement part is a cost-effective solution to restore your exhaust monitoring system.

OEM-Grade Construction and Strict Factory Testing

Our replacement 8200771294 oxygen sensor features a high-precision ceramic oxygen sensing element and reinforced anti-vibration internal circuit. It is engineered to withstand high exhaust temperature and vibration during stop-and-go city traffic and highway cruising. The outer protective housing, wiring harness and electrical plug connector are fully dimension-matched to Renault OEM and DENSO factory specifications, preventing wire cracking, water ingress and intermittent signal dropouts.

Every finished O2 sensor unit goes through high-temperature aging testing, oxygen signal calibration and waterproof sealing inspection before shipment. This quality check eliminates common flaws found in cheap generic sensors, such as unstable oxygen readings, slow signal response and early premature failure.

Exact Vehicle Compatibility & Interchange OE Numbers

This post-cat exhaust oxygen sensor is a direct replacement for the below Renault gasoline vehicles. Interchange Part Numbers:

• Renault OE: 8200771294
• DENSO cross: 234-4448

Fitment List:

• Renault Clio III
• Renault Modus
• Renault Twingo II
• Renault Kangoo II

As a core component of the exhaust emission monitoring system, this downstream O2 sensor allows the ECU to evaluate catalytic converter performance. A faulty downstream oxygen sensor will trigger catalyst-related DTCs, cause failed emissions testing and illuminate the check engine light.

Core Benefits of Upgrading to the 8200771294 Oxygen Sensor

Replacing your malfunctioning factory post-cat O2 detector with our pre-calibrated WJIECO 8200771294 oxygen sensor delivers noticeable performance improvements and protects expensive catalytic converters. Unlike low-cost aftermarket sensors that repeatedly trigger fault codes due to poor calibration, our unit provides steady, accurate exhaust oxygen data for the vehicle ECU.

Reliable sensor measurements enable the engine computer to confirm catalytic converter function, avoid false catalyst fault codes, and keep your compact car or light van compliant with emission regulations. After installation, you can clear oxygen sensor related trouble codes and pass state emissions inspection.

Plug-and-Play Installation, No Dealer Programming Required

A key advantage of this 8200771294 oxygen sensor is its true plug-and-play design built for compatible Renault models. This replacement part requires no ECU reprogramming, manual calibration, wire cutting or complicated mechanical modifications.

Installation works well for both professional repair garages and DIY vehicle owners. Simply remove the old sensor from the exhaust pipe after catalytic converter, apply anti-seize compound on threads, align and screw in the new sensor, reconnect the factory wiring plug, then clear stored fault codes using an OBD diagnostic scanner. After a short normal driving cycle, the exhaust emission monitoring system will return to stable operation without recurring warning alerts.

Every WJIECO sensor passes complete functional testing before leaving our factory. If you need a durable, high-precision and affordable OEM replacement downstream oxygen sensor matching Renault OE 8200771294 and DENSO 234-4448 for your Renault Clio III, Modus, Twingo II or Kangoo II, our 8200771294 Oxygen O2 Sensor is the ideal choice to restore your exhaust and emissions monitoring system.
