2009 Chevrolet Trailblazer Air Flow Sensors

The ACDelco GM Original Equipment Oxygen (O2) Sensor is a GM-recommended replacement for your vehicle’s original component. The Oxygen (O2) Sensor is a special feedback sensor on your vehicle’s exhaust system. This sensor measures the proportion of oxygen in the exhaust gases. Using this measurement, the engine management computer can adjust the air/fuel ratio near the optimum value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. This original equipment oxygen sensor has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors. When you are looking for a match to GM Original Equipment specifications in a replacement part for your GM vehicle, trust ACDelco to get the job done.

Product Features:

• Detect oxygen content in the exhaust gases to optimize emissions and fuel economy
• GM-recommended replacement part for your GM vehicle’s original factory component
• Offering the quality, reliability, and durability of GM OE
• Manufactured to GM OE specification for fit, form, and function

The Delphi Wide Range Oxygen Sensor is an integral component in the engine management system, helping provide accurate engine control and system diagnostics. It measures the air-fuel ratio of exhaust gases over a wide lambda range. Its five-wire, two-cell design enables higher signal resolution with greater accuracy. An integrated heater and alumina-zirconia element facilitate a fast light-off, allowing earlier closed-loop operation compared to conventional conical oxygen sensors. Designed to accommodate a variety of fuel applications, the poison-resistant coating of the Delphi Wide Range Oxygen Sensor helps improve accuracy and durability in harsh exhaust environments, while minimizing deterioration of the sensor characteristics over time. Its uniquely designed planar element technology and integral heater enhance resistance to thermal shock and help the sensor achieve fast light-off to help manufacturers meet current and more stringent future emissions regulations. The sensor’s greater accuracy and a fast transient response time help provide greater engine control, and help improve fuel economy and drivability.

Product Features:

• High signal resolution and low pressure sensitivity help provide precise engine control
• Integral heater enables faster light-off for earlier closed-loop operation
• Unique planar element design enhances thermal shock resistance
