SENSORS

Delphi Wide Range Oxygen Sensor
The Delphi Wide Range Oxygen Sensor is an integral component in
a gasoline or diesel 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 fivewire, 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.

Benefits

•

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
Fast response helps improve fuel economy
Industry-leading poison-resistant coating helps achieve better
durability and truer reading of exhaust gases

Typical OSL Output Curve

Delphi's Wide Range Oxygen Sensor with
planar element technology helps provide
accurate engine control and system
diagnostics.

Note: The Delphi Wide Range Oxygen Sensor characteristic output is linear to percent oxygen in the exhaust.

Typical Applications
The Delphi Wide Range Oxygen Sensor is an integral part of diesel and gasoline engine management
systems where additional control is desirable. With different shielding options, the sensor can be tailored
for specific applications in passenger vehicles, commercial vehicles, motorcycles and other engine
applications.
