This heated upstream O2 sensor uses magnetic induction to deliver fast, stable readings as soon as the exhaust reaches operating temperature, helping the engine control unit (ECU) optimize fuel trims and emissions.\u003c\/p\u003e \u003cp\u003eWith OEM reference 39210-23900, this sensor matches the original specification for reliable fit, quick installation, and durable performance in typical driving conditions—from daily commutes to highway cruising. Replacing a tired sensor can reduce exhaust emissions, improve idle stability, and restore smooth acceleration by ensuring the ECU receives accurate oxygen data during cold starts and steady-state operation.\u003c\/p\u003e \u003cp\u003eDesigned to withstand the automotive environment, the WEIDA upstream O2 sensor features a robust construction and a precise sensing element. By providing timely oxygen measurements in the exhaust stream, it helps prevent fuel over-enrichment or lean conditions that can trigger fuel economy loss or check engine lights.\u003c\/p\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUse case: Replace a failing upstream O2 sensor on 2003–2009 Hyundai Elantra or Kia Spectra 2.0L I4 to restore proper fuel mixture and improve driveability.\u003c\/li\u003e\n\u003cli\u003eInstallation tip: Verify the OEM No. 39210-23900 matches your vehicle’s part number to ensure correct fitment before installation.\u003c\/li\u003e\n\u003cli\u003eMaintenance tip: After installation, perform a short drive cycle to allow the ECU to recalibrate fuel trims for optimal performance and emissions.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: WEIDA AUTO PARTS\u003c\/li\u003e\n\u003cli\u003ePart: Oxygen Sensor (Upstream, 5-Wire, Heated)\u003c\/li\u003e\n\u003cli\u003eSensor Type: Magnetic Induction\u003c\/li\u003e\n\u003cli\u003eWiring: 5-Wire\u003c\/li\u003e\n\u003cli\u003eApplication: Upstream sensor for 2003–2009 Hyundai Elantra and Kia Spectra 2.0L L4\u003c\/li\u003e\n\u003cli\u003eOEM No.: 39210-23900\u003c\/li\u003e\n\u003cli\u003eOrigin: Japan (JP)\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x WEIDA AUTO PARTS Upstream 5-Wire Oxygen Sensor for Hyundai Elantra (2003–2009) and Kia Spectra (2.0L L4)\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWarnings\/Reminders\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure correct sensor orientation during installation and avoid contact with hot exhaust components.\u003c\/li\u003e\n\u003cli\u003eDisconnect the battery and follow vehicle service manual guidelines when replacing sensors to prevent misfire or ECU faults.\u003c\/li\u003e\n\u003c\/ul\u003e \u003cp\u003eDiscreet trust statement: Since 2002, intercyprus.com has earned trust for quality and reliability.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"InterCyprus Trading Ltd","offers":[{"title":"Default Title","offer_id":52391951368534,"sku":"32952082572-Default Title","price":54.15,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0530\/0604\/1274\/files\/H85ab62b2a6d144a0b5dd2b4690767523v.webp?v=1768928573","url":"https:\/\/www.intercyprus.com\/fr\/products\/5-wire-lambda-o2-oxygen-sensor-upstream-fits-for-2003-2009-hyundai-elantra-kia-spectra-2-0l-l4-no-39210-23900-3921023900","provider":"InterCyprus Trading Ltd","version":"1.0","type":"link"}
