Part Number: OXY-SEN-9075
Product Type:
Oxygen Sensor / Lambda Sensor Denso 234-9075 cross-reference
Type: Wideband / Air-Fuel Ratio AFR sensor or upstream O2 sensor depending on application
corresponds to:
Denso 234-9075 Oxygen / Air-Fuel Ratio Sensor
Type: Heated wideband AFR sensor 4-wire / direct-fit in many listings
Used mainly as a pre-catalytic converter upstream sensor
This sensor is commonly fitted across various vehicles where Denso OEM systems are used, including multiple Toyota / Lexus / Honda / Mazda applications depending on calibration.
This sensor measures oxygen content in the exhaust before the catalytic converter and sends live data to the ECU to:
Adjust air–fuel mixture in real time
Improve fuel economy
Reduce emissions
Protect catalytic converter efficiency
Help maintain correct combustion ratio lambda control
Oxygen Sensor / Lambda Sensor – Part Number OXY-SEN-9075 Denso 234-9075.
High-quality wideband air-fuel ratio sensor designed for accurate exhaust oxygen measurement before the catalytic converter.
Commonly used in various petrol vehicles equipped with Denso engine management systems Toyota, Honda, Mazda and others depending on engine variant.
Provides precise air–fuel ratio feedback to the ECU for optimal combustion, improved fuel economy, and reduced emissions.
Ideal replacement for faulty oxygen sensors causing check engine light, poor fuel consumption, or drivability issues.
Please ensure compatibility by matching OXY-SEN-9075 or Denso 234-9075 and connector type before purchase.
