It is a 5-wire wideband AFR sensor with a 620mm cable, supplied with a direct-fit factory-matched connector for plug and play installation. NTK is the world's largest manufacturer of original equipment oxygen sensors. \u003cstrong\u003eThis is a wideband air fuel ratio sensor and is not interchangeable with a conventional narrowband oxygen sensor.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"wl-pull\"\u003eFrom November 2004 the VQ35DE moved to a wideband air fuel ratio sensor in the upstream pre-cat position. Unlike a conventional narrowband oxygen sensor which simply switches rich or lean, the wideband AFR sensor produces a continuous linear output signal that tells the ECU precisely how rich or lean the engine is running at any point in time. This allows the ECU to make finer and faster corrections to the air fuel mixture for improved fuel economy, reduced emissions, and sharper throttle response. A faulty AFR sensor has a direct and immediate effect on fuel management and drivability.\u003c\/div\u003e\n\u003cdiv class=\"wl-diagnostic\"\u003e\n\u003cp\u003e\u003cstrong\u003eCommon symptoms of a faulty upstream AFR sensor:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e• Check engine light with upstream O2 or AFR fault codes (P0130, P0131, P0132, P0133, P2A00, P2A03 or similar)\u003c\/p\u003e\n\u003cp\u003e• Increased fuel consumption\u003c\/p\u003e\n\u003cp\u003e• Rough idle or hesitation under acceleration\u003c\/p\u003e\n\u003cp\u003e• Reduced engine performance or sluggish throttle response\u003c\/p\u003e\n\u003cp\u003e• Failed emissions test\u003c\/p\u003e\n\u003cp\u003e• Note: a faulty AFR sensor can also falsely trigger catalytic converter efficiency codes (P0420 \/ P0430)\u003c\/p\u003e\n\u003c\/div\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eProduct specifications\u003c\/h2\u003e\n\u003ctable class=\"wl-table\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eAFR722-EE20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eNTK (NGK Group)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor type\u003c\/td\u003e\n\u003ctd\u003eWideband air fuel ratio sensor (AFR)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003ePre-catalytic converter (upstream)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of wires\u003c\/td\u003e\n\u003ctd\u003e5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable length\u003c\/td\u003e\n\u003ctd\u003e620mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eFrom November 2004 build date\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector\u003c\/td\u003e\n\u003ctd\u003eDirect-fit factory-matched\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSold as\u003c\/td\u003e\n\u003ctd\u003e1 sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eWhy NTK\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eNTK is the world's largest supplier and manufacturer of original equipment oxygen and AFR sensors, supplying the sensor technology used in many Nissan vehicles as original equipment\u003c\/li\u003e\n\u003cli\u003eWideband AFR sensor technology produces a continuous linear output signal for precise real-time air fuel ratio measurement, enabling the ECU to make faster and more accurate fuel delivery corrections than a conventional narrowband sensor\u003c\/li\u003e\n\u003cli\u003eSuperior dual-coated platinum interface and advanced ceramic element for fast light-off times, accurate output, and improved durability\u003c\/li\u003e\n\u003cli\u003eIndividually tested during manufacture to guarantee quality and reliability that meets or exceeds OEM specifications\u003c\/li\u003e\n\u003cli\u003eSupplied with a direct-fit factory-matched connector for plug and play installation with no wiring modification required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eInstallation\u003c\/h2\u003e\n\u003cdiv class=\"wl-install\"\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003eDifficulty\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003eIntermediate\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003ePosition\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003ePre-cat upstream\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003eTools required\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003eO2 sensor socket\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"wl-install-box\"\u003e\n\u003cp class=\"wl-install-label\"\u003eWiring required\u003c\/p\u003e\n\u003cp class=\"wl-install-val\"\u003eNone\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003chr class=\"wl-divider\"\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\n\u003cdiv class=\"wl-fitment\"\u003e\n\u003cp\u003eNissan 350Z Z33 DE · From November 2004 (VQ35DE · 3.5L V6) · Pre-cat upstream · Sold as 1 sensor\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cp style=\"font-size: 0.88em; color: #6b7280; margin-top: 6px;\"\u003eSuits VQ35DE 350Z built from November 2004 only. 350Z DE models built up to November 2004 use the NTK OZA817-EE1 instead.
