Air/Fuel Ratio Sensor

The Denso 234-9013 is an OE-identical Air/Fuel Ratio (AFR) Sensor engineered to deliver precise readings to your vehicle's Engine Control Unit (ECU). By providing an exact AFR response, this sensor contributes to enhanced engine performance, lower exhaust emissions, and improved fuel economy. Constructed with durability in mind, the Denso 234-9013 features an advanced sensing element. It includes an aluminum-oxide trap layer that safeguards the ceramic from silicone and lead poisoning, thereby protecting the platinum electrode. A double protection cover ensures the sensor operates at the optimal temperature for faster response times and shields the ceramic element from contaminants. The robust stainless steel housing offers resistance to corrosion and contamination, while a porous PTFE filter allows necessary atmospheric oxygen to enter the sensor without compromising its integrity. Key specifications for this sensor include a threaded mounting type, a Zirconia material composition, and a 4-wire, heated design. The wire length is 203mm (8 inches) with a thread diameter of .711 inches. This thimble-type sensor utilizes an OE-type connector for a direct fit. Denso backs this sensor with a 12-month warranty. This Denso 234-9013 AFR sensor is specifically designed for select Honda Insight models from 2001-2006, functioning as an upstream sensor. It is manufactured by DENSO, the Original Equipment (OE) manufacturer for these applications, ensuring a direct fit and reliable performance.
