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.
Delphi Wide Range Oxygen Sensor Benefits
